Euphemism for masturbation.

The act of one man ejaculating into another man's hand, then the man with jizz in his hand using it as lubrication to jerk off. After he cums in the same hand, he bitch slaps the other man in the face getting cum on him.

This act is only gay for the man getting slapped because he is the one getting a handful of spunk slapped around his cocksucker like a total faggot.

To Bitch Slap That Ho!

When you shit in your hand and you slap a bitch in the face!

Getting a peer, co-worker, or supervisor a corporate write-up up just because you dislike them or because they have caused you some inconvenience.

After investing your time sweet talking and wining and dining a woman. Bitch slap her during Sex and hold on tight (preferably by her hair) whilst she goes mad and tries to throw you off.
The challenge is to stay on board as long as possible and to ideally break her. Compare times with your friends and earn extra credibility for your time on the bitch slap bronco with female weightlifters or bodybuilders who are larger and stronger than you.

To lightly smack someone across the face in admonishing manner for doing something lame, reminiscent of Will Smith slapping Kevin James in the Movie "Hitch".
