Quadruple Decker

When you poop in the toilet tank, toilet seat, floor, as well in the air vent.

"Hey bro my friend on a discord call is looking for all the deckers on urban dictionary"

"Oh cool, don't forget to tell him about the quadruple decker!"

THE UPPER DECKER

Upper Decker Blumpkin AC Slater

This act requires both a male and female to perform. A male takes a crap in the upper tank of the toilet while performing a delicate balancing act, and getting his cock sucked, as the female takes a crap on the toilet facing the wrong direction. Much like how AC Slater sits in a chair when he's at the Maxx.

I got my girlfriend so drunk that I was actually able to convince her to perform the Upper Decker Blumpkin AC Slater with me while my buddy hid in the closet and video taped the performance!

Double Decker

To leave an Upper Decker in the toilet tank, and to leave a Floater in the bowl. This can either be a two-man job, or performed by a single person who breaks his payload into two segments. The result is that the water in the bowl will be brown, and the water that comes from the tank during a flush will also be brown.

An upper decker wasn't enough for that place, so for good measure I left a double decker.
