Well, hitting women is not usually socially acceptable. Maybe if you didn't know it was a chick (like yesterday, I yelled at my friend Eric to get his attention "ERIC!!" I said. but then she turned around and i was like, "o shit, thats not a male") or if you were being legitamately assaulted, but i can never think of a time in my life when a female was hitting me in a way that made me want to hit her back.
