A very rare phenomenon in which the woman begins puberty in a manner where she thinks for herself and realizes that video games are, in fact, very enteraining. Female gamers generally do not follow the social norm of how to dress, what make-up to wear, how to style their hair, so on and so forth.
My girlfriend is a Female Gamer, as is my mother (oddly enough) and a handful of chick-chicks (not guys playing as chicks) that I know.
A girl who enjoys playing video or computer games more than she does worrying about getting a boyfriend or applying makeup. So for those of you who think they don't exist, eat it, because I am one.
I am a female gamer
Will never exist, seriously.
