THE UPPER DECKER

The upper decker is when you shit in the tank of the toilet.

Man.. Tom is being a dick! I'm going to give him the upper decker before we bail!

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!

Hipster Upper Decker

The act of defecating in the upper tank of a toilet, exhaling vape into the tank and then sealing it for a honeydew, kiwi, and cool mint surprise!

Thomas left a hipster upper decker in the toilet at the party that was surprisingly refreshing.
