When you go into a resturants or public places bathroom and have to shit and so you go in the toilet tank and when people go in their they'll be wondering about the small and never be able to find it.
Herget and Zach went into Zaxby's, Herget powerbombed the bathroom while Zach upper tanked it. Man what a mess.

The act of taking a shit in the top part of the toilet while a girl is giving you head at the same time.
Last night my girlfriend was so drunk and she was pissing me off and she surprisingly let me pull off an Upper Blumpkin

A knocker-upper was someone whose sole purpose was to wake people up during a time when alarm clocks were expensive and not very reliable.
"M. Smith earned 6 pence a week as a knocker-upper using a pea shooter to shoot dried peas at the windows of sleeping workers in East London, 1930s"

Diarrhea drenching the outside of a toilet from the top down. Let loose your diarrhea all over the toilet. Start on the closed top of the tank and move on to the closed lid. Wanna up your game beyond the upper decker? Try the Upper Reserve.
The bathroom was so fancy an upper decker would not be enough; so I left an Upper Reserve. Shit soaked toilet yo.

Sitting on a toilet AC Slater style while defecating, and performing fellatio on an individual in the act of upper decking the same toilet.
It sounded like a good idea last night, but we spent all morning cleaning the tank after trying out the upper blumpkin.
