The usual bunch were sitting around the Student Union, drinking Coke and talking and harassing each other between classes when the talk got around the slapping someone.

I told one of the women that if they ever did have to slap someone to cup their hand. That would concentrate the force of the slap.

The next Monday she came in, laughing like crazy. Seems like over the weekend she and her boyfriend had had a discussion and he had said something to the effect that a woman couldn't slap him hard enough to cause him pain. So she slapped him as I told her to.

He passed out from the pain. Seems like slapping that way concentrates the force into the trigeminal nerve -- and that's EXQUISITELY painful.

He never made any such comments again and she was glad to take the wind out of him!
