This is the single most disgusting nasty offensive thing I've ever read. And it's bloody amazing!
This piece of fanart for Team Fortress 2 references a throwaway line in the game about Sniper's "Kangaroo Wife", but rather than go the obvious route it subverts it... then crosses it... then crosses it again, all while being bloody hilarious.
The same artist does it again, this time with The Spy.
Thirty Hs is a Harry Potter Troll Fic which takes Black Comedy and Rule of CoolUp to Eleven, in the process crossing the line so many times that it just may win the award for line crossing. The opening line features Dobby cutting open an astronaut's head with his groinsaw. Yes, a groinsaw is exactly what it sounds like. Yes, that is what happens in the very first line. Somehow, it manages to escalate from there, with an early appearance by Fuckslayer, Harry's guitar which is described as, "a guitar from a dimension where all screamed for naught, wrought from the silver heart of heaven's false promise, laced with vessels that pulsed with angel's menstrual blood, hewn from the horns of Satan's generals."
Basically what happens is a Doumon¬ bewitches all the tamers except for Takato into becoming the embodiment of each of the seven deadly sins so we now have Rika Nonaka as a frieking avatar of lust!. The whole thing is just so WRONG it's hilarious, and Ruki and Chaos' comments make it that much better.
When Link goes to save Takara and Varia, he is confronted by camouflaged soldiers. He drives them into a fear-driven frenzy and uses magic to jam their guns so they are forced to bash and pummel each other to death. The bastards deserve it, but the drama ends the moment Link reasons there's "something missing" and, for no reason other than his amusement, follows up with a casual instruction: "Mouths only."
Following on from that scene, the shadowdemon goes on to graphically mutilate and kill 12 women and 28 children (the families of the scientists responsible for Takara and Varia's torment) on Link's orders. Deadly serious? Yes. Morally questionable? Absolutely. The shadow demon musing on a name for itself, then treating the survivors' shocked silence the way an inexperienced comedian would regard an audience that wasn't laughing? Hilarious.
Still, no one spoke, which seemed to make the creature genuinely uncomfortable.
"No? Shade? Shady?"
The men stood silent, tears and mucus streaming down their faces, but the creature continued. Its flippancy and their inability to make it respect their loved ones' lost lives made them cry harder.
"The Hand, then? Handy? No? None of those?"
In Bella Swan Pregnant And Furious, Satan gets beaten so hard by Bella (yes, thatBella), that his internal organs start coming out of his mouth. He is left "toothless and organless", "coughing blood and trembling with pain."
The NSFW short story "Peach's Double Life", which details in rather explicit manner Princess Peach's sexual affairs between MarioandBowser on the occasions she's being rescued by the former and being "kidnapped" by the latter. If that wasn't enough, it then goes into a detailed account of "Bowser Jr's spiky shell, unknowingly, used for the sexual pleasure of Peach, as she births him."
As with most interpretations of the character, The Joker absolutely skips rope with the line in one of his two brief appearances in Angel of the Bat. Most of the presentations of death in the story are very dark handled seriously. But then The Joker kills some workers and employees of Arkham Asylum, his reasons for doing so including "Making bad meatloaf", "Stealing an extra package of cream cheese" and "I just never liked you." When confronting The Fundamentalist (and later Big Bad) Daniel Lebowitz, Joker says he doesn't like religion because it promotes bigotry, and he prefers to kill everyone instead of specific people.
Supper Smash Bros Mishonh From God makes all gays and 'lesbians' into licentious Hollywood Satanists, who want nothing more than to turn others gay by 'rapping' them, so that they change to being homosexual. Anytime this happens, it is done completely inaccurately, and is extremely over-the-top that it becomes a complete laugh.
RWBY Volume 3 was viewed by fans as tragedy with all the crap the protagonists go through in the second half. Someone decided to pay tribute to it by showing the events....while playing the RWBY Chibi theme over them.
