Get the upper deck mug.The upperdecker is a prank that you can pull on a friend or loved one, or more likely someone who deserves it. An upperdecker is defined as defecating in the upper tank of a toilet, allowing it to fester for as long as possible and sending a chilling brown residue into the bowl upon each flush.
At a party where they run out of beer one might like to leave an "upperdecker" to show their disapproval.

Get the UPPERDECKER mug.This one takes practice. This maneuver requires a toilet with a tank above it, like the ones in most homes. Instead of crapping in the bowl, you shit in the tank. Now don't flush. When the following victim flushes, the rancid waste fills the bowl. If you play your cards right, it may ferment. Great prank for those lame partys.

Get the Upperdecking mug.A vengeful act of defacating in the tank of a toilet so as to odorize the bathroom with every flush for weeks until found. This is usually done at parties where you don't like the host/hostess.
"everytime I flush the toilet my bathroom wreaks, someone must have left an upperdecker, when I said the parties over go home..OH man! they did."

Get the upperdecker mug.A man takes the upper-back of the toilet off and sits on it. A woman gives him a blowjob as he takes a crap in the back of the toilet. After crapping and the blow job is done, he puts the lid back on the toilet.
An unsuspecting person comes in later and uses the toilette. When they flush the toilet it fills with brown water from the crap the man took in the upper deck.

Get the upper deck mug.This technique is for the most skilled of slaterer's. One must be nimble and quick in order to accomplish this feat. It involves combining the classics "slatering" and the "upper decker." You sit on the top of the toilet in the AC slater position (from saved by the bell) and take a hot steamy dump in the upper deck.
Jorge: Hey man, what's wrong. Why is your face all bruised on your left side?
Carlos: Shit man, I was slatering the upper deck on your can and I fell off.
Jorge: What the hell does that mean man. What's that brown shit on your shirt and pants.
Carlos: Shit.
Jorge: You are f'd man. Why do I hang out with you.
