Although usually used as a punishment for bad sex, a ham sandwich can also be something for kinky and wierd chicks. It begins with a man walking up and down a girls body with his legs stratilling her body (she is laying down and he is standing) he then shits all over her untill he is done. He then continues by pissing all over her body. He finally completes the sandwich by laying on top of her.
Dude, that chich was so bad last night i had to give her a ham sandwich.
