The effect of an accumulation of being fucked over too many times. It is when one cannot handle the bullshit of guys anymore, so they take matters into their own hands. It is when one fucks over, rather then becomes fucked over. It is when one does not have feelings nor give a shit about others. It is when one is a heartless bitch.

Girl: Because these niggas taught me how.
