Underfags

People who are obsessed with the indie game Undertale by Toby Fox. They have a horrible tendency to say things like "welp", "hoi", "boi", etc. They are also noted to be extremely toxic and get butthurt incredibly fast, this us due to most of the fandom being nercophilliac 12 year olds who lashes out on you saying things like "l0l uR gOnNa haVe a Bad TiMe!!1!11!!".

Underfags are so annoying.

underage drinking

The only thing that makes adolencense worth while.

If you don't drink underage at some point in your life, you are considered uncool.

The only thing worth in life is parties and a lot of underage drinking
