A girl who thinks she is better then the average girl. she thinks she is a different breed. a whole different species. and that everyone loves her.

a pick me girl is a really annoying girl who will says she's one of the boys and says that she does not wear makeup and thinks that she is the only girl in the world who plays sports and videogames.

A girl who likes to shame other girls just so she can be like “one of the boys” they also like to copy all the things a boy she likes would like. Basically a person who thinks she is special when she’s not

Essentially, it is a girl with internalized misogyny that is willing to turn against her own gender for the attention and approval of men. They ignore blatantly sexist behavior, even sometimes participating as to not seem unfunny or uncool. They also try their best to separate themselves from "other girls" because they see other girls as bad or basic compared to themselves, who are inherently special and therefore deserve male attention.

pick me girls, the ones that think every guy is obsessed with them and think they care about her feelings, say will say the stupidest things and act “corky” for any guy to like them.
