Putinha
Portuguese (Brazilian) for "little slut".
Porra cara, essa menina e uma putinha! (Damn dude, that girl is a little slut!)
P3rv3rt B3ar, I feel your pain. Been there. Go get hammered and nail her best friend or sister if she has one. It will make you feel marginally better, at least in the short term.
Just don't stay hammered.
