I slipped and told my twin sister this. We joke about this to this day.

My brother and I used to play a game where we'd trade "Your mom" jokes for as long as possible in the presence of people who knew us. The goal was to keep the retorts coming right as a comeback until I finally popped him. Not because I was offended but because it got pretty annoying when he responded to EVERY FUCKING THING I said with "Your uncle" (that's it, not "Your uncle is ______" just "Your uncle").

One joke this troper devised when thinking of ideas he'd like to see in a ''Series/DoctorWho'' AbridgedSeries. #QUOTE#'''Doctor''': We can't afford the stock footage.\\ '''Colonel Mace''': Isn't stock footage really cheap?\\ '''Doctor''': Your mother.

I've got one prepared for a very specific situation, although the first bit is a bit obscure: #QUOTE#''Guy'': You're a giant pussy! #QUOTE#''Candy Entrails'': You lie! I don't live between your mother's legs! I have visited a lot, though.

At Space Camp, one of this troper's teammates was supposed to "go insane" during a simulation, so he screamed and cried for his mother, and ended up opening the airlock in space and killing everybody, all while shouting "Mama! Mama!" So this troper turned to him and went "You know what about your mama? Your mama's so stupid that when it says 'Sign here' on forms, she writes 'Scorpio'!"

The absolute worst and best "Your Mom" joke this troper has ever done: without thinking, he said "Your mom has x" to some girls, who were talking about '''breast cancer''', thus leading to "Your mom has breast cancer." Needless to say, I was mortified, ''especially'' when it turned out that the person with breast cancer said girls were talking about was one of the girls' mother. However, they both laughed as well, saving this troper a very bad day.

This troper loves giving this response with her sister. Just for the obvious inconsistency. We've also been known to say random things like "your gallbladder."

This troper has taken to telling her younger brother tus madre, which, if my middle-school Spanish courses hold true, roughly means, "Y'all's mom."

My cousin has a variant that he uses to end conversations at the point where they start to get stupid. "That's what your mom said last night while I was having sex with her."

This troper has been declared the patron saint of Your Mom jokes, probably because she's so sadistic about them. Seriously, she's kind of infamous for responding to them with "My mom's dead." (She is, but it was years and years ago. People are just catching on that this troper's not offended when she says that.) The best exchange yet: #QUOTE#This troper: It's time for drawing-on-the-board! #QUOTE#This troper's friend: It's time for your mom! #QUOTE#Troper: I would be highly surprised if it were. #QUOTE#Friend: ...It's time for your zombie mom! #QUOTE#Troper: Ha. Mombie.

Well, it's good that you can laugh about it. A friend of mine lost his mother in the last year, and I have a hard time stop telling him "Your mother"-jokes. It makes me feel like an insensitive bastard.

When this troper was about eight-years old and in a chorus, the girls in the row behind her were telling 'yo mama is so fat' jokes during a break. Being young and incredibly naive, this troper thought that the girls were talking about ''her own mother.'' She asked them to please stop. They didn't. She turned around and decked the lead girl in the face for - she thought - insulting her mother. Even better, she didn't get kicked out of chorus, because the director didn't like the lead girl, who was a trouble maker! (For the record, she felt awful about it afterwards, mostly because she thought she'd get kicked out of chorus, and tearfully explained to her horrified mother why she'd punched another girl IN THE FACE.)

Too many "Your mom is a ___" jokes in this troper's social circle eventually led to "Your mom is a mom!" Also, this troper recently had the following exchange with her brother: #QUOTE#'''Brother:''' Don't be such a caveman! #QUOTE#'''Troper:''' Your mom's a caveman! #QUOTE#'''Brother:''' ... She's your mother too, you idiot.

While discussing languages at work, someone asked some colleagues from different middle-eastern countries if swearing was understandable between different Arabic dialects. Two said no, the third pointed out that the word for mother was the same in all dialects so they would get the idea.

This troper sometimes raises Your Mom jokes to DaDa levels of crazy, it usually involves taking a random sentence, then taking a random word form this sentence and then just adding 'Your Mom' at the front. #QUOTE#'''Twin:''' You wish you had a guitar #QUOTE#'''Self:''' Your Mom's a guitar #QUOTE#'''Twin:''' ''has long given up using logic with me''

This troper raised 'your mum' to an art form last year and was able to catch people insanely off guard with it. Then it got predictable, unfortunately.

Similar to some of the above examples, I had an example where I used this in what was probably the least appropriate context possible. #QUOTE#'''Me''': Your mom! #QUOTE#'''Friend''': Is in the hospital. #QUOTE#'''Me''': Oh... Oh my god. Is she okay!?!!

This Troper was hanging out with a bunch of his friends and cracking terrible ThatsWhatSheSaid jokes, until one friend said that the most recent ThatsWhatSheSaid joke was "so easy it was almost unethical." Gasping with laughter, I responded "YourMom was so easy it was almost unethical!"

This Troper remembers firing one off several years ago that was just loaded with FridgeLogic. #QUOTE#'''Me''': How much did you pay that whore to be your mother? #QUOTE#'''Bystander''': (in between bursts of laughter) ''How does that even make sense?!''

This troper's English lessons are often entertaining due to a boy in her class who enjoys this trope far too much. #QUOTE#'''Teacher:''' Today, we're going to be looking at the use of oxymorons in war poetry. Does anybody know what an oxymoron is? #QUOTE#'''Student:''' (Boy's name here) is an oxyMORON! #QUOTE#'''Boy:''' (missing the lame pun) Your mum's an oxymoron.

He will do this with any word in the English language. And some besides that.

I just went and fudged yo' momma.

My mom constantly does yo' momma jokes to me. Fridge logic tends to appear.

This Troper tries to avert this, using 'your dad' instead (or, y'know, an ''original'' insult). She also knows a guy who uses it in response to everything, which has become the cause of much face-on-palm action.

Your mom is so fat, when she stepped on a rainbow, it turned into skittles.

This Troper (who is normally TheStoic) once became so fed up with someone who used "Yo Mama" jokes every fifth sentence or so, that when he tried one on her, she gave him her most serious look and said "My mom's dead." This scared the everloving crap out of him, for she looks pretty dang intimidating for a woman (Note: Her mother is most definitely not dead.)

This troper read a really good one on Sikipedia: "Dear NASA, your mom thought I was big enough! Pluto"

In a situation that I felt it would be too unwise to make this kind of joke, I still replied "Traditionally I should now change the subject to your mother." when someone mentioned an object two meters wide and over a century old. I got away with it.

ThatsWhatSheSaid.

Zing!
