The female version of a fuckboy. They don't catch feelings. Enjoys being single so they're not tied down to one guy in particular.

A girl that thinks she's hot shit. She's a little conceited and likes to make you think that she's for real when she's really just playing with your head for amusement. It's a game to her and she's really good at convincing everyone that it's not and that she really cares about you. She's the kind of girl that will try to get back with you just to feel like she's winning against someone else, and so no one else can have you. She might seem to care, and she might even care a little, but she doesn't really REALLY care. Could probably end up winning best actress award for all the bullshit they fake.

A girl who thinks shes hot and the shit and attempts to show it without trying but it is obvious that she is. They tend to be extremely unreadable and mess with guys heads. Though they claim to not be a hoe they're usually closet whores and will cheat. They will show no emotion to a guy that cares but fall in love with guys that just want to bang and bail.
