- Hilariously occurs In-Universe (and Out) in this The Most Popular Girls in School fanfiction:
"Uh-oh." Deandra promptly dumped the fries in the trash amidst her nervous laughter, and the boss walked off, satisfied. As soon as he was gone, Deandra plunged her prosthetic hands into the trashcan and began eating with utter euphoria.
"…That is so wrong." Shay said, sickened and shielding her eyes.
"Ya think, Shay?" Mackenzie averted her gaze and bent over, clutching her stomach.
- Thousand Shinji: Any scene involving Rei's worship of Nurgle, Chaos God of Decay. Especially the Ireul battle and Rei's transformation into Mama Reigle.
- In Axis Powers Hetalia there is a comic, which later expanded into so many spin-offs it's practically a fandom of its own, known as the World Financial Crisis Gangbang. The cast blames America for the economic crisis... so they (with the exception of his little brother Canada, thank god) gang rape him. And that's not even going into the "America's revenge" fics, where he makes it his priority to torture and murder his rapists in the worst ways the author can think of at the time.
- Poké Wars. The authors sometimes get a little too detailed and graphic with the descriptions of what undampened Pokémon attacks do to living beings...
- Cheerilee's Garden. In particular, Sweetie Belle's death, although the others could probably spark some unpleasant reactions as well.
- Project Mobitropolis, Shax the Raptor's gestalt of Sonic 2 and the backstory behind the SATAM continuity, has an in-universe moment of nausea induction when Prince Martin is deceived by Robotnik and roboticized and subsequently murdered/deactivated, and it proves to be horrifying enough to make Sonic himself puke in revulsion.
- Hivefled; the prequel Reprise was intentional Torture Porn, and while the sequel's not so graphic it does carry over.
- The Prayer Warriors repeatedly point out that they don't bury the enemy's dead. One has to imagine all those bodies, laying around rotting and getting eaten by scavengers. Some of the death scenes also count.
- Virtually any time someone is stoned to death, especially if you're familiar with how it works in Real Life, as it's a long and painful death.
- Chiron is killed and eaten by the residents of Camp Half-Blood.
- "Idiot" and "Benjamin" (the representations of two people who hacked into the author's account) are impaled and set on fire, and cut to pieces and fed to a dog, respectively.
- Ginny is blown to pieces by an explosion, and Michael even specifically describes some of the pieces of her that he finds.
- Grover's first death in Threat of Satanic Commonism; both his legs get broken and he gets disemboweled by a spear.
- Sonic X: Dark Chaos. Anything involving Dark Chaos Energy and what it does to unprotected human bodies, and pretty much anything involving the Shroud. Much of the gore leads into this as well.
- His Shroud infection gives Tails literal nausea fuel, as there are several scenes of him feeling too sick to get out of bed or vomiting into a toilet. His Shroud transformations are just as disgusting. Just to expand, his first transformation includes him ejaculating uncontrollably before his semen turns solid and starts slithering around his body.
- Total Drama Equestria, where the cast of Total Drama (who are in pony form at the time) is seen eating grass in Equestria. Now think about this fact. Where the ponies live in Equestria, there are no bathrooms. No toilets, nothing. So... where do you think that the My Little Pony cast go to the bathroom? The Total Drama cast thought about that same question... and quickly spat out the grass they were eating.
- From Maim de Maim, we get:
- Ryuko nearly losing her lower jaw in Chapter 12 is described in very stomach churning details.
- Same goes for Charlie Tapatio's demise in Chapter 15 and the aftermaths of Dr. Batty's murders in Chapter 19.
- Ragyo Kiryuin and Dr. Richard Batty having (off-screen) sex in Chapter 22.
- NES Godzilla Creepypasta: The Organic level. It's a level composed of incredibly realistic, fleshy textures, as well as equally-realistic mix-and-match, grotesque creatures. Worst of all, the boss is a sheep fetus combined with a dog skull.
- Just about every chapter of What Lies Beyond the Walls contains at least a mention of faecal matter, and sometimes far more than a mere mention.
