When a video game becomes popularly hated due to its fandom as opposed to the game itself. Part of cringe culture. Often results in a hatewagon.
"Let's play Fortnite!"
"Eugh, why Fortnite? That game sucks. The community is filled with whining kids."
"Didn't you have the same reaction to Undertale? It was a good game but the community ruined it? Isn't most Fortnite hate just another Undertale effect?"

Playing undertale is a term used for a form of homosexual intercourse, in which the dominant male forces their hand fully into the "underground", another term for the other mans asshole.

Undertale Fandom Syndrome(UFS), is a horrible disease that is founded in major fandoms. First discovered in 2014, it was created in its first stage with the FNAF fandom. It horribly spread when undertale became popular. Common symptoms include: comic dubs, weird fetish art, and annoying obnoxious children/preteens. Unfortunately, UFS has became a parasite that is sent to feed off hosts and cannot be treated or cured. The following fandoms that suffered the same fate include but not excluded: FNAF, Undertale, Cuphead, Bendy and the Ink Machine, Hazbin Hotel, and recently, Friday Night Funkin'.
Person: yo dude have you seen this game called Friday Night Funkin'?
Another person: yeah man that shit is really great!
Person: yeah it is, unfortunately the FNF fandom is making Pico x BF yaoi.
Another person: shit! Another game fell into Undertale Fandom Syndrome

Undertale last corridor grinders are confirmed NOOBS, the reason is, they grind because they are too lazy to get exp without grinding and they also can't fight as sans, and they also might camp for exp when you're not grinding, they risk getting banned and they think that reporting won't work, but, you can just report them in dark wood's stuido discord server, BTW even if they have good stuff and like that doesn't mean they're good at the game, they have bad comebacks and they keep begging to grind, they don't know we will report them in discord, but don't tell them we can report them in Discord it's really your opinion but always destroy these noobs.
