A girl I was very close with for two years was that way ... she got a power trip after having a group of them following her every whim, and putting up with crap from her just for a chance she'd give them That Look. She was the kind of girl that had 8-9 guys a month hanging around ME and then asking "you think I should go for Misty?", including my own cousin
Finally broke enough hearts for them to learn and pass the word around ...
