Canonist

Fandom terminology for a person who only likes what is canon.

I love writing fanfiction but my friend hate it because she is a canonist.

Infinitesimal

YOU MAKE ONE MISTAKE AND THIS IS WHAT HAPPENS!

Oh he misused the word infinitesimal last week! He thought it meant really big but it actually means really small!

Shank

Shank is so fucking hot

Fanphobe

A fanphobe is a person against fandoms and fangirls, they are typically canonists (People who only like what actually happens in a story, not fanfiction or AUs).

I was going to show her my fanart but she's a fanphobe.
