I've never been slapped in anger by a woman nor have I ever slapped one in anger.
I did however slap a woman in a theatrical production as called for by the script. In an effort to be as realistic as possible I got slightly carried away and failed to pull my punch. I split the girls lip and knocked her to the ground. The script then called for me to kick her in the stomach and storm off stage.
I was frantically waiting for the scene to end so that I could find out if she was ok and apologize.
I was not very well liked by the audience.

They reacted with a loud boo every time I came on stage after that.
I was a hit.
