This troper, for reasons not worth elaborating, had his character kill a murdering fellow party member in a ''DungeonsAndDragons'' game with the line "This is for Kay! Who's blonde!"

This one has a bad habit of doing this to both puppy-kicking RPG villains and FightingGame bosses.

This editor has a good guess, based on the fandom, that at least one player of ''TheElderScrolls: Oblivion'' said "This is for during the battle with [[spoiler:Bellamont.

I said the same, but substitute with [[spoiler:the Cheydinhal Sanctuary. Purification's a horrible ritual...

When this troper's ranger character in a ''Wushu'' powered ''{{Spelljammer}}'' game, an ex-mercenary who suffered at the hands of a sadistic torturer who tortured one of her last crews to death, finally caught up to the scumbag during a job for her current crew, the final blows were delivered for each of her crewmates that he had murdered, including a guy she'd been quite fond of at the time.

After my brother said that you can't believe everything on the internet after I had said something that I didn't even say I read off the internet, I hit him. My brother believed that it was for saying that NewMediaAreEvil, but no, it was for a different reason.

A friend of mine sometimes brings around his Xbox (even though I've got my own) and hooks it up to the second T.V. in my room and then uses the extra ethernet slot so we can technically play splitscreen xbox live, makes it a lot funner, but anyway. Playing GTA 4 online, we were free roaming and started getting a cop chase going, naturally some other players teamed up with us, all went well for quite a long time, but suddenly we found ourselves cornered by an unnaturally large number of police, little ammo left, some of us on low health, and with only one escape car left, we got here with 5 men and two escape cars, in our hold out we blew up one to kill some cops, I prepared for a Bolivian army ending to our spree, but one such player has another plan, he turns his gun on my mate and kills him, then tells us to rush the car since we can all now get away, we rush for the car, they all clamber in and over mic yelling "GET IN, GET IN!" the police are pulling up, they're still waiting, I pull out my rocket launcher. "This is for Joker." (part of his online tag.) They go to speak "Wha?" Kaboom, I'm left with half health, down to 30 rifle shots and 2 rockets, with police closing in, and due to it being proximity chat I can't tell what they were planning for me, I managed to hold out until my friend managed to find a car and drive me back out, sheer luck, and the single most awesome line I delivered over xbox live, some pretty good events followed, but they're hardly relevant to the page.

This Troper did it while fighting Flux in ''FinalFantasyX''. At first they were serious ("This is for [[spoiler:Biran, this is for and this is for [[spoiler:Kinoc!") - but, y'know, that fight goes on for a long time, so silly ones started to slip in. Think I finally finished him off in the name of Gok Wan.

This troper invokes this when he gets into fights on IRC. He's invoked the entire cast of NeonGenesisEvangelion on one occasion, and AngelMoxie on another.

This troper was playing ''Portal'' and was up to the final fight against When dropping each of [[spoiler:GLaDOS' cores into the incinerator, he remembered to shout "This is for the Weighted Companion Cube!"

This troper ended up crying "This is for Emilio!" during ''TraumaCenter: Second Opinion'''s final... boss fight.

This Troper was talking to his friends on a phone while doing that segment, and while the next-to-last of the string-things, he added "And this is for me, who just failed the level." It was a CrowningMomentOfFunny among his friends.

While playing ''{{Okami}}'', this troper was heard finishing a major boss battle with "That was for and Rao, you nine-tailed bitch."

Dwarf fortress. This troper had his favorite dwarf die via a rampaging elephant. As he sent troops for the final charge against the beast, he whispered, "This is for Urist."

TheLegendofZelda: MajorasMask. Ladies and gentlemen, you get to the final boss armed with the Fierce Diety mask and a notebook full of names you spent the last three days assisting, and you have a bit of a speech to give. "This one's for the bombers, this one's for the Rosa sisters, this ones for that monkey..." And, eventually, up to the point "This one's for the Indigogos, this ones for Mikau, Daramani, that Deku scrub, and this one...Oh, this one is for the last three weeks of playing this game." Cue the final blow.

This troper's best friend, who has white hair at the age of 17 and is 7'8", enjoys making fun of how scary and intimidating he is. So he thought it'd be funny this last Thanksgiving to 'carve' the turkey by stabbing it repeatedly while yelling, "Why do you always have to betray me, Demitra? (that's the name of his sister) Why?! Why?! This is for all the shit you've put me through! For calling me Snorlax! For killing my hamster! For wearing sandals! You BITCH!" and then he stood there, panting and breathing very hard for a moment before quietly sitting down, plastering a polite and normal smile on his face, and calmly eating his stuffing. He's been invited to Thanksgiving for the next six years for that one.

This troper did this on his 2nd attempt at beating Skeith in .hack//Infection. The very first time, I was not only defeated by it, but my PS2 died on me shortly after; scaring up the disc. The 2nd time, once I got far enough to use Data Drain, I proceeded to shout "This is for my PS2! Open up wide and suck on my obelisk!". In fact, the latter part has become my traditional pre-Data Drain sentence when fighting the major bosses in the games.

This troper invoked this trope by thinking, "For Aryll!" when he smashed the Helmaroc King in the face with the Skull Hammer after it blocked his way.

I remember a couple of these moments:

Resident Evil: Darkside Chronicles, when I finally killed Alexia, and remembered "And that one's for Steve, yah bitch."

Ocarina of Time: This one's for Rauru, this one's for Saria, Darunai, Ruto, Impa, Nabooru, Zelda, Navi, Jabu Jabu, Deku Tree...and this one's for the last 9 dungeons, yah bastard.

(I enjoy ending things with the "yah bastard" note)

At the end of the school year, I burn all of the work I've done over the year. "And this is for the hours of my life I'll never get back."

Mira-chan used a variation of this on a punching bag, dedicating a series of powerful blows to herself. "Let's see how ''you'' like it when life does this to ''you''!"

This troper, while playing Fire emblem 9, Boyd died on chapter 6 at The Boss's hands (who got a critical). On the final chapter Ike Aether'd Ashnard straight away. "This is for Boyd, you bat-shit little freak!"

On the last mission of HaloReach, would occasionally dedicate each of his shots to the other fallen members of Noble Team[[spoiler:, namely Kat, Jorge, and Carter. Minutes later This Troper added "And '''that''' was for [[spoiler: after taking down the bastard Zealot who killed him.
