Really, a depressing stage in a female's life. This is a person who will get crazy over (insert name here*) and will do anything to get closer to them, including stealing hair, stalking, tatoos all over the body, a shrine, suicide, bulemia, cutting themselves, copying fashion, etc.
In acuality, fangirls hang so close to their obession in hopes of being rewarded by sex. (I'm not kidding).
P1: OH MY GOD IM SUCH A FANGIRL OF JUSTIN BEIBER.
P2: Bitch, stop cutting yourself and get some senses, he will never sleep with you. He lacks a penis anyway.
