Dirty Brownie 

Diarrhea on the floor. Most likely from an animal or drunk person. Usually to be expected at a party, (especially at a bad one) in the closet at or around the coats; although unexpected on your bedroom floor. It's smelly and volatile, so keep a distance of about 50 feet in order to breathe.

Me and Luke laughed so hard when the dog left a dirty brownie on Selena's new shirt. That dog was our hero.
