A dude sits atop the toilet tank and craps in it, facing forward. A woman (or man, I guess...) sits on the toilet backwards and also crals as s/he performs oral sex on the guy seated atop the tank.
What were you two doing in the bathroom so long?
I expelled every fluid imaginable thanks to getting an upper-decker double blumpkin.

Get the Upper-decker Double Blumpkinmug. Similar to the Upper Decker, the Double Decker involves taking a shit in the victim’s toilet, not flushing, then repeating the process in the tank. The end result is the unsuspecting victim flushing the lone turd, only to be accosted by a stream of liquid feces into the bowl. This is far beyond an innocent prank, be sure the victim deserves it, as there’s no going back.
Allen was house-sitting for Sam and had a party at his house...he was only caught because somebody left a Double Decker in Sam’s toilet.

Get the Double Deckermug. Performing a European Double-Decker involves a male and female deficating in the bowl and resevoir (respectively) with the male straddling the resevoir, thus giving him access to perform cunnilingus on the female.
Brad and Angela just got back from a European Double-Decker in the bathroom. You can tell by his white mustache and brown soul patch.
