What can I say? I am just a '''HAPPY CAMPER''' is all!

This basically is what happens whenever I am put in an incredibly uncomfortable situation. Often when my mom and sister start physically hurting one another, all I can do laugh, laugh hysterically.

This troper used to laugh hysterically when he was injured. I was once curb stomped onto the ground. I slowly got up laughing all the while. It was HighOctaneNaightmareFuel for everyone, even me, because I just Couldn't stop laughing. My laugh can basically be described as the Kira laugh, with a smoker's voice and whooping cough. So I sort of seemed like the bastard child of the Joker and Charles Manson. It doesn't help that no one really knows much about me, even my Nakama hasn't figured me out, to be honest, neither did I.

This troper is normally able to hold it together. Occasionally I'll have a bad, tear filled breakdown. There's been a few times where it's been bad enough to instead leave me in a Joker-esque mood, laughing while thinking about the various ways I can violently murder people (mostly my family). I've also got a bit of this permanently, as when I'm in a bad mood I'll, while not laughing out loud, basically be like that on the inside.

This troper's cycle of anger goes like this:

Unhappy

Pissed

Shouting and screaming

Quiet, soft laughter

Insane Joker-type laughter.

This is basically the cycle of every fight this troper and her sister have ever had, with the shouting and screaming often escalating into actual physical violence. The fight will end after one of us makes a semi-witty observation and winding up on the floor laughing our asses off.

No, no. That's not laughing mad. Laughing mad is when after you kill your sister you have a Blue Screen of Death moment, and you can only laugh, because that's the only thing you can do to remain sane. Except, by that point...

Well then what the hell is it? It's not this definition, certainly not EvilLaugh either. I looked on one of the other ones, and it said something about Bipolar, but that's all I reckon. It's likely something, one way or another. *raises eyebrow and cradles chin*

This troper was having a very rough time...she needed money to find a new home, as her roommates were forcing her out of her current one, and would be out in the streets unless she was in a new house by two weeks. After spending the entire week bottling everything in, feeling miserable because no one would let her move in with them without rent money up front, the troper was called to the financial counselor. Turned out, that very day, she had received her scholarship money, used for rent. She spent the next two minutes staring blankly ahead, laughing her head off.

Once this Troper was living a real Hell: I was bullied, depressed, didn't have a single friend and constantly arguing with my mother. Then one day, after having one massive fight again and being harassed in a hallway we got out math tests back and I had failed it. I waited until the lesson passed and then proceeded to laugh maniacally and stare blankly, because the test had been the last straw that broke the camel's back. But fortunately, IGotBetter. / When I get extremely pissed off or start panicking it's usually accomppanied with silent, anxious laughter that isn't loud or theathrical, but it's ''damn creepy''.

Dear god, this sounds like something from my life as it had been. You have my simpathies :(

This troper apparently does this during her memory-lapsed-BerserkerRage-BewareTheNiceOnes moments. Which means, that when I start cackling like the Joker, it means that someone's about to get seriously injured... AND I WON'T REMEMBER DOING IT. (My friends have witnessed this once and tell me it's the single most unnerving thing they've ever seen.)

This troper doesn't remember the events that led up to it, but once she snapped and started laughing herself silly and looking back on it, is absolutely terrified of herself in that state.

This troper has never had an extremely severe case of this, but she has been known to emit some damn scary psychotic cackles when she just can't take severe frustration from a problem anymore.

This troper has been gaining touches of this more over time. I'm pretty sure RealLife causes SanitySlippage.

This Troper just had one of his first attacks of this. He was snickering slightly after playing KaizoMarioWorld's first level (and dying, again and again, on that first trap), but did not burst into laughter until this CompleteMonster math problem (below). After spending an hour or so on Part B, attempting to cancel out the monstrosity known as the unit normal vector... he just spotted a sine squared-cosine squared point in one really messy radical. After everything canceled out to N(t)=(-cos(ωt),-sin(ωt),0)... {{Laughing Mad}}ness ensued. #QUOTE#Let a, b, and ω be positive constants. Let g(t)=(a cos(ωt),a sin(ωt,bt). #QUOTE#a) Find explicitly the arc length parameterization h(s) of the curve. #QUOTE#b) Find the unit tangent vector and principle normal vectors at an arbitrary point h(s). #QUOTE#c) Find the curvature κ(s).

The story continues: Another bout of madness when Part C comes out to (aω^2)/(a^2ω^2+b^2).

This troper has issues dealing with stress, and has a tendency to just freakout out of seemingly nowhere. The form of the freakout is generally a crapshoot between curling up in a corner shivering and muttering, or hysterical laughter that can't decide if it wants to be giggles or shouts and shifts between them randomly.

This Troper too. I once got really angry at a group of children. After about a few moments of shouting at them into silence and scolding them, still shouting angrily all the time, this troper had a sudden "revelation" of how ridiculous the entire situation was, and began softly giggling. Soon, the giggles became louder, and this troper was reduced into laughing hysterically while everyone watched with wide eyes. Needless to say, it frightened even the naughtiest children into quiet, meek puppets.

This might be kind of a conversation of ADarkerMe in this troper's case. Sometimes, he has this evil side that will come out spontaneously and let out a really big EvilLaugh, usually while doing something to someone that's been annoying him for far too long. Normally used while playing video games.

This troper does this when she loses, and let me tell you, my laugh sounds like the Joker on crack while burning down a puppy orphanage and stabbing a nun. Needless to say, my laugh is so Nightmare Fuel, that I scare myself sometimes.

This troper uses a dark "heh, heh heh" on occasion when annoyed, in a sort of "I can't ''believe'' what fools these morons be" way to make the situation seem more meaningless, but once when the troper's mother was being particularly obtuse, the troper was seconds away from self-mutilation, destruction of a dresser, or both, and instead ended up dropping to the floor while laughing madly (and increasingly) and weeping, both at the futility of... well, everything, but certain aspects of that situation in particular. Unpleasant, but the resulting high (from either endorphins or oxygen deprivation) made it possible to finish the conversation. Eventually.

This has become at least a part of each of This Troper's emotional expressions, from amusement to rejection. Why, I'm not entirely sure.

A fairly minor example, compared to the ones on this page. I was playing Harvest Moon: FOMT with the watering can fully upgraded. However, I didn't realize the [=AoE=] you can do with it, so I spent year upon year (I upgraded the can fairly early) watering all my crops seperately until, by chance, I found out about the [=AoE=]. Though the laugh wasn't as insane as really pissed off, it still sounded quite insane.

This troper reacts in this manner to just about EVERYTHING, whether positive or negative. Since it runs the full range of evil laughs, it scares people. Lots. Not that it's any different from my NORMAL laugh...

ThisTroper reacted like this after he lost his job, girlfriend, almost his apartment due late bills and was drown in a sea of depression all in the same week. Well ThisTroper remained "calm" so far just to out of nowhere burst laughing like psychotic lunatic in the middle of a crowded street and, almost needless to say, after that ThisTroper was almost put in a psychiatric ward by his friends. ThisTroper almost never stresses out, but when it happens it's either LaughingMad or something like UnstoppableRage. Either way none come with any sign of warn, it simply bursts out of ThisTroper.

This Troper has done this on several (BSOD-type) occasions. I assure you, it's quite unnerving...

This Troper was doing this (although it was more of a chuckle) when he imagined about stabbing and slashing one of my REALLY annoying classmates. Then my friend offered me a slice of cheesecake.

When this troper gets angry, it usually starts out with screaming at the tormentor, then he starts chasing them, with a mix of batshit-insane cackling, swearing a blue streak, snarling like some crazy beast, and just plain screaming. Oh, and as he gets closer to the target, he gets louder and more insane.

This troper has moments where she just laughs while screaming and it's hard for her to even tell which she's doing more. It comes almost out of nowhere but generally happens during psychotic episodes and sometimes will be about something she hears, something that's "happening", or just snap out of nowhere it feels right and it happens. Often after or during this is some very odd behavior. On the other hand... she sometimes manages to just sleep 3 days straight after.

Several months ago, this troper had to take a test which she was pretty sure she'd fail due to not really understanding the material. When it was over, she felt a bit better knowing that it was over and walked to her next class...to take another test that she'd completely forgotton about from worrying so much about the first one. She spent the first ten minutes of the period with her head down laughing as quietly as she could.

Oh dear deity yes, for this troper. Possessed of a double bass voice with a decent falsetto range, the signature hysterical laughter - which sustains itself to ridiculous lengths through the pressures of nervousness and embarrassment - ranges wildly, and with much switching between shrieking peaks and barking lows. Coming from a quiet loner whose only commonly-known personality traits are a liking for violent and morbid humour and the inability to smile anything but a slasher smile... it is, I am told, quite an interesting spectacle, if a little... disconcerting.

So ''that'''s how it's called ! When I'm sad, I'll usually begin to cry... Until I feel every bit of pain disappear, and begin laughing at my own sadness. And when I say "laughing", I mean manical, uncontrollable laughter, much more high-pitched than my normal laugh. And every time I learn new details about humans being bastards, such as torture, genocide, etc... I will only laugh madly and desperately. Although it might be a consequence of those JadeColoredGlasses I usually wear...

This troper cries or laughs if she get angry enough, she suppresses cry due to habit and ends up laughing in a... very scary manner.

My friends and I have a bit of a RunningGag about turning into TheJoker. Our college is pretty tough, and it really is kind of scary when someone starts laughing uncontrollably at something that isn't all that funny because she's just really stressed out or hasn't been getting enough sleep.

For some reason, whenever I'm fighting with someone, I get a horrible case of loud, cackling laughter. It doesn't help that it renders me a shaking mess and won't stop for at least a few minutes once it's started, even if I'm completely enraged and/or in immense pain. On the up side, most people are afraid to fight me now.

This Troper laughs madly when in physical pain, and is actually one step before crying for her. She once got it into her head that she wanted a tattoo that would take four hours to complete. She was alright for the first three, but by the time the artist got to coloring the damn thing, her mind apparently decided she was being tortured and tried to distance itself from the pain. First she started to cry and whine. Then she started to laugh insanely. Then she started rambling incoherently for the next hour or so... The tattoo was finished, though, and was worth every bit of pain, though it did need a touch-up later which wasn't nearly as bad.

Variation: my cousins and I decided to play a prank by getting in an elevator and laughing non stop everytime someone got in there. At first, the person joined us asking what the joke was about, but when we kept on laughing they started to look as us like we were some kind of nutcases and their smiles cracked. That made us laugh even more.

This troper has some...mental strains, so to speak. For instance my only remembered dream in the past 5 years is of a man systematically pulling out his nervous system and unraveling like a knitted jumps. In graphic detail that only a biology student could inflict on themselves. My laugh sounds like several dubs of Kira's combined. I checked. Believe me on this one, listening to examples of laughs is a pass time of mine. It's primarily the japanese, the french and...you know what let's just say I sound like Kira when I laugh. When I laugh in this manner then it means my usual catatonia has been surpassed and that my own reasoning has disolved. Last time it happened I lost the majority of my memories up to that point.

This Troper recalls at least one 20-mile hike with a few Scouts, on which the trail snaked up and down lots of hills. As in, lots. It was nothing I couldn't handle on my own (being in decently good shape at the time), but the others were starting to complain, and after rounding a corner and seeing ''yet another'' 45-degree incline upwards, I broke out into loud cheering accompanied by a psychotic grin. Apparently it was a slightly unnerving experience for those scouts...

For some bizarre reason, I tend to grin or start giggling when really nervous. I'm not really sure why, and I never seem to realize I'm doing it for quite a bit. It's a little weird. Everyone seems to assume it's this trope, especially when, say, somebody's just been hit in the face hard enough to start crying in gym class, while I'm actually worried about them. But.. I'm not really insane, just slightly weird, right? Riight?!

My ''cats'' drive me to this constantly. One moment I'll be screaming at him to go away with that toy he keeps dropping on me and the next I'll be laughing and sobbing at the same time.

Maybe he just wants to play?

Generally happens for this troper when she is up late into the night/morning, running on very little sleep and high amounts of caffeine. Actually laughed like a madman for thirty straight minutes for no reason whatsoever.

I (forget the This Troper nonsense, won't work here) am currently in the process of writing a novel in which the antagonist is completely nuts. I tend to use method writing, where I force myself into sympathy with the character's emotions. I was writing a scene from her Start of Darkness and began to feel dizzy. Anyway, I went back to my dorm, and began to read the character's lines to see if I'd gotten it right. The scene I'd just written ends with a slow laugh, starting with childish giggles and finishing with cackling screams. I started into that part, the dizziness returned, I started laughing...and came within a millimeter of completely losing my mind. Ever since that incident, I've felt like I'm on the edge of Laughing Mad. This has been going on for two months.

I Got Better.

This troper fell into the water when trying to cross a rope-swing bridge and (temporarily) broke his camera and soaking everything on him. His response: being upset for a few minutes, and then laughing uncontrollably, then going back to upset.

Occaisionally this troper experiences this with very little stimuli. It isn't that I'm pushed over the edge (I hope), I just can't stop laughing sometimes.

Ah, just remembered a throughbread example. I broke down one terroble November day and couldn't stop laughing for a distrubingly long time.

This Tropette once had a paper due the very next day, and her printer just wouldn't print. She'd spent untold hours on this paper and gotten no sleep the night before trying to finish it. It began with her yelling and swearing, then ''screaming'' and swearing. She finally got the printer to work and print double-sided to boot... only to discover that it was printing the other side ''upside down''. Cue Mad Laughter, complete with anguished hair-clutching.

This Troper once had one of the worse days in her entire life in which she lost all sanity for roughly 10 minutes. An ex-boyfriend caused the intense grief, and we had been arguing for months and months on end even when we agreed to remain friends. I was depressed for nearly an entire year because of him. Finally, I sent him a long anger-filled e-mail to dismiss him from my life, in which I proceeded to point out every stupid and hurtful thing he's ever said to me and every single way I could find that he's ever wronged me. At first, I thought I felt nothing, because I was just... so drained from all the effort. Afterwards, however, I went absolutely nuts whilst voicechatting with another friend. And I'm not exaggerating or joking: It was a hellfest of emotions. First, there was crying and screaming. Loud crying and screaming... it just started out of nowhere as I was silent. Then I started laughing. Really loudly and maniacally. For about five minutes. Alternating with the crying and screaming, at the same time. It was the only time in my entire life where it had happened, and the friend and I agreed that it was absolutely ''scary.''

This happened to me only once in my life, but it could happen again, I don't take any form of raised voices well if they're used in a threatening tone, so following an arguement involving my parents, I began to laugh and cry hysterically at the same time before just falling completely silent for about an hour, when my mom finally walked up to me, instead of saying anything or re-assuring her, I just burst into the most twisted-sounding psychopathic laugh she'd ever heard...did I mention our family business is ''a haunted house?'' I can't remember it, but if it can scare someone who works with psychopathic laughter on a seasonal basis...yeah.

Ever since I was young, I had a way of laughing or smiling uncontrollably when I was confronted with bad news. I also laugh when I get panic attacks. My parents thought I was sick in the head when they saw me laughing after my cat died, but I was actually very sad. I also laugh when I see scary and disturbing things, but that's Fetishist}} something else...

I've had a lot of various roller coaster twists in my life, and for the most part I've reacted just as you would expect for all them... but occasionally? My brain decides to give me a step back and I just start laughing. At it all. Everything I've gone through in my life runs through my mind, and it's just... funny. How all of it happened to me. And I laugh, and laugh, and laugh. No idea why, because a lot of it is horrible, but I can never help it.

This troper's cat brought a live mouse into the house tonight, and somehow it got into this troper's room. Her father set a trap for it in the closet, where the mouse had scurried off to. This troper wasn't TOO affected by this, but then she heard a ''snap'' and some painful squeaking… She's been giggling hysterically for nearly twenty minutes now.

This Troper has THE Joker laugh and bad anger problems to boot. When I get mad at someone I just start laughing hysterically until someone brings me back down to Earth. My friends now have a routine where one of them takes me aside and asks me if I need to go back to Arkham. On a completely different note, I sprained my ankle WALKING on the carpet and it hurt so bad I just laughed, and every time I stepped on it, I laughed.

AHAHAHAHAHAHA!
