upper decker

Also referred to as 'Going Up Top,' the act of taking a shit in the tank of a toilet. Common courtesy not to flush. Used TP should be placed inside drawers, magazines, or the tank itself. Feel free to throw in any other items you can find in the bathroom during the process.

"Man this party sucks... I'll let 'em know how I feel with an Upper Decker"

"Dude!! You shit in my toilet" -> "Where else did you want me to go?" -> "Not in the top part you fuck!!"

"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!"

Faux Decker

The more-merciful relative of the dreaded Upper Decker.

A Faux Decker is executed by:

1) Opening the rear tank of a toilet and dropping in a piece of novelty rubber dog poop;

2) Pouring in 1/2 cup (120mL) of instant iced tea mix into the tank as well;

3) Replace the lid and leave the Faux Decker for the next unsuspecting victim.

Upon flushing the toilet, a brown stew will be unleashed, horrifying the user and leading them to open the rear tank...only to see the fake poop and surmise they have been struck with an Upper Decker.

The Faux Decker is a more sanitary prank than the insidious Upper Decker, but you get almost the same shock-value from the Faux Decker as you would the original.

Dude 1: "I pranked my Mom on April Fool's Day with a Faux Decker!"

Dude 2: "Why a Faux Decker not an original Upper Decker?"

Dude 1: "DUDE, she's my Mom! I wanted to freak her out, not make her disown me!!"

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.
