Do girls flirt by being a sarcastic smartass?

I'm just wondering, this girl I like is just so awesome at it and can keep up with me pretty well and I don't really see her doing this with anybody else. She is also mean (playfully) to me. She seems to smile a lot and make a lot of eye contact while we are doing it, is there anything here?
