Is this hot or am I making a mistake?

I've twice hung out with a chick that has bad *** down to a science. Its punk rock, its sexy, but its kind of threatening. she's the kind of girl that will start a little trouble with other girls just to make them uncomfortable. The kind of girl that doesn't lecture you about responding aggressively to a jag off on the road - she joins in. She is in my face, too. From day one she has made it clar she thinks I'm hot enough to get with - but that I shouldn't take anything for granted. She has also made it clear she is very capable of kicking my balls, and she knows to kick a guy sexy, kick a guy funny, and how to kick a guy like she means it. The threat of a kick in the balls is very much a part of how she flirts - which is something she seems to be keen on doing with me. worst part is, i find it unbelievable hot - which is good - but man i'm starting to think like a freak and i don't know that that's a good thing. I think if we hang out again, I'll end up making a move and it will be well received. but i'm not a hump and dump kind of guy. is this girl too nuts to get involved with?
