chocolate stamping 

what animals do when they rub or place their dirty buttholes on things leaving something that resembles a stamp made our of their rear chocolate. A perfect examples are dogs who have exposed buttholes like pugs and they like to sit or lay and they move later leave a chocolate stamp behind.

my dog monk loves to sit on me but he backs his butt up on you and one of these days im sure im going to get a chocolate stamping on my clothes.

Chocolate Grape Stomping 

To bend some poor unsuspecting douchebag over and lube up his or her ass then proceed to lube up your feet all the way the way up to your knees. Slowly insert one foot at a time in said douchebags cornhole. When both feet are snugly inserted start mashing and stomping away at the chocolate grapes.

Dude, just because the coach likes to get a good chocolate grape stomping, it doesn't mean I should be the one to do it.
