Brown Tumbler

When one takes a dump in one's dryer and turns it on turning it into the brown tumbler.
It's in the same category as a Upper Decker.

At a party go into the laundry room take a dump in the dryer, preferably a top load, and proceed to turn it on and do the Brown Tumbler.

Brown Tumbler

A sexual act which involves defecating on your partner and wrestling with him/her so as to share in the feces.

Let's do a Brown Tumbler tonight. This chicken taco platter should give me plenty to work with.
