A drunken prank of knowingly shitting on one's toilet lid to be discovered later by a unsuspecting person. Usually done at a friends house you just don't give a fuck about or at a random house party. Basically one upping the Upper Deck.
Dude go check out the platter I just left in the bathroom, grab your shit let's get out of here .
Who the fuck left the platter in my bathroom, I went to take a piss and all I see is a shit mound on the toilet lid.
