Pretty much every time somebody randomly stuffs on undertale. It's a quirky rpg game that at it's worst is a solid okay. I don't get what the deal is with this seething hatred people have for this game and I'm pretty much settling with the fact that it's because it's popular and a lot of people talk about it.
this doesn't just apply to undertale, it also applies to literally everything with a sizable following (furries, sonic, mlp, and fnaf, to name a few)
fandoms are annoying, but hatedoms are just as bad, if not worse
also it's funny how people who hate x fandom are doing exactly what they're calling fans of x fandom guilty for- bringing up discussion of x fandom when it isn't even relevant
