Fangirl

Very commonly misunderstood to be hyper-active and stalker-ish. But in fact, they are mostly peaceful introverts who don't have the courage to ask anything from any person in real life, and are most likely to live inside the internet. They may seem like a quite breed of cats at first sight, but if you insult them, remember that they have already planned 72 ways to murder you, 25 ways to kidnap you and 16 different ways to hide your body without getting caught by the law. This is mostly inspired by their obsession with a certain fandom.

Closely related to Nerds, at times. Male version of a Fangirl is known as Fanboy, and they're very scarce but existent nonetheless.

Jaz: Oh my gods! I just killed my ex-boyfriend, it was an accident I swear! What do I do now??
Sadie: Gods? Are you in the PJO fandom? It's okay, I'm a Fangirl myself. I watch Supernatural, CSI and Boston Legals. You've come to the right place, follow me.
