Get the upper triple decker mug.The act of taking a shit on wax paper, wrapping it up and putting it in the freezer until solid frozen. Then using the frozen turd as a time delay shit bomb, drop it in the upper tank of a toilette. The Shit Agent will have time to escape and the results won’t happen until hours after he is long gone. Once the shit thaws and someone flushes the toilette, it will fill the bowl with brown water and mission is complete.
I was over Jill’s house and she had a couple people over . I wanted to upperdecker her toilette but didn’t want to get caught. Since I have mad spy skills I used some frozen shit I stashed in her deep freezer and upperdecker 007’d her toilette , giving me plenty of time between the time I left and when Allyson went in and flushed it.

Get the Upperdecking 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.
