A girl who decides one day to leave her BF for another guy.
Uses the next BF for a week, leaves him.
Uses the next BF for 3 days, leaves him.
......after about a good month, you find out she's gone with 10 guys. and alot of unknown
explanations.
In other words,
the theory of using guys to get w/e you want -whether
physically, materially, mentally etc- and discarding them like a sock after its used.
