Why do some men like "bitchy" women?

I'm not saying its a bad or good thing, I'm just curious. what about a bitchy girl is appealing to many guys? I think we have all seen this so lets not pretend its only a small minority of guys who like this type of girl.

And yes we know girls like certain kinds of guys as well, but that's not what I'm asking. I'm asking what is the appeal of bitchy girls. maybe you know guys who like them, even if you personally dont. Just try to actually answer my question, basically. I know sometimes answerers drift away from the question!

thanks :)
