Typically a teenage girl with an obsession towards something: a show, movie, book, person, etc. There are three types of these
fan girls:
Normal fan girl:
Perfectly normal girl, may even be pretty. Has an obsession, but keeps it to herself. Might read
fanfiction, have a blog dedicated, several
merchandise related to this obsession. Safe to approach.
Crazy fan girl:
Relatively normal girl, sometimes pretty. Really enjoys her obsession. May talk about it every once and a while. Reads fanfiction daily, and writes it. Dedicates
1-2 hours of her life to this obsession. Owns several pieces of merchandise. Cosplays every once and a while. Approach with caution.
Completely insane fan girl:
Needs to go to a mental facility, usually does not care about beauty in any way. Rarely pretty. Loves her obsession (typically anime) more than anything in the world. If you took away her internet access, she would
retreat to her army of merchandise related to her obsession. But, after a few hours, would die of lack of fanfiction. Cosplays almost every weekend. Dedicates
6-7 hours of her life to her obsession. Spends the rest of it thinking/dreaming about it. If you encounter this type of fan girl,
call the police immediately. DO NOT APPROACH.
