chocolate tattoo 

The benevolent act of wiping your dirty anal hole on the face of an unsuspecting, passed out drunk person, usually a friend. This is done in hope of leaving a brown streak known as the chocolate tattoo. A chocolate tattoo can also be done on a person's clothing if your shit won't adhere to the face.

I got off easy last night. The Chughumper was looking to give me a chocolate tattoo, but he couldn't find me.

Chocolate Donut Tattoo

When a person presses their asshole against another person or object, leaving a shit ring that resembles a donut.

"Charles pressed his ass against my arm and left a chocolate donut tattoo."
