Scat, or that shit where people like sretch and shit and it looks awful, theres this one artist who does doujins and i fucking hate his work because he makes everything look so fucking gross with prolapses and vomit scat etc
Agree with scat as many are saying, would also add in insect stuff. Been a handful of games that looked good otherwise but as soon as it shows that it has a bunch of insect content that's an immediate nope from me and would just rather they not be in any game tbh.
