A girl who is a gamer:
Will seldom ever let you know they're a girl, unless it actually matters.
Is actually good at the game.
Doesn't need or want white knights.
Doesn't want attention.
Is there to play the game.
A gamer girl:
At the drop of the hat remind you in ever possible way that she's a girl.
Generally has no idea what the fuck she's doing, and doesn't want to get better.
Needs and wants white knights so she can act like a cunt and be counter productive.
Wants every last bit of everyone's attention at all times, will "flirt" with guys non stop to get it if needed.
Isn't there to play the game. Honestly I have no idea what a gamer girl is there for other than to piss the actual gamers off and some how have fun at the same time.
