The ham slam is a premeditated act. You must place a ham steak (thick, flexible and boneless) between the matress and box spring prior to any sex act taking place. Have sex in the doggy style position and when the man is about to come, he removes the ham without the woman knowing. He comes on the ham and when his partner turns around to see what he is doing, he slaps her in the face with the come soaked ham.
