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
