Undertale Fanbase

Young lunatics that have way too much time to draw rule 34 of their favorite undertale characters. They don't go outside much and skip school to masturbate to their trash undertale porn.
Guy : I saw someone from the Undertale Fanbase outside, unbelievable.

Undertale

A game where people are a character where they can pick a name. The characters true name is FRISK. Also, teenage girls who haven't ever played the game are obsessed with an obese skeleton and make him have a glow in the dark pp
Person 1: Hey do you know undertale?

Person 2: Oh that weird ass game where teenage girls cream over a random fat skeleton?
