Stompin' Grapes 

The Act of Defecating while in the shower, and using the feet to assist in dispersal of fecal matter down the drain. Reminiscent of ancient wine makers. May be shart related.

Dude I totally lost control in the shower, and ended Stompin' Grapes.

stomping the grape

When you shit in the shower and have to squash it down the drain with your toes

Wife: Damn it Joe, it stinks like shit in here.
Husband: No worries, just stomping the grape before you walked in

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.

grape stomping 

A common Dutch fetish, but also quite popular in Belgium and northern France, involving the purposeful squeezing of feces, occasionally canine, through ones toes for your partners sexual satisfaction!

I was finally able to go grape stomping at the dog park in Amsterdam!
