The act of defecating inside the water tank of a toilet.
Step 1: Go to the home of your mortal enemy. Ask to use the bathroom.
Step 2: Approach toilet and remove the water tank lid.
Step 3: Step on the sides of the toilet and squat over the water. Carefully take a massive dump. Wipe your ass and dispose of toilet paper in the trash bin.
Step 4: Place water tank lid back on the toilet.
Step 5: Escape.
What happens? With each resulting flush, it will fill the bowl with a chunky brown water. Its the gift that keeps on giving :)

Get the Upper Decker mug.The act of sharting in public and then taking your shit pasted underwear off and disposing of it in the tank of the toilet
Man 1. Boo boo has been gone for awhile
Man 2. He's probably taking a shit
Man 1. He farted before he left so likely
Person in question....we need to leave
Later admits he put his shitty underpants in the tank of the toilet of a public setting to avoid being embrassed
Now their shit covered under pants are worse then discovering actual shit in the tank
The upper decker delux

Get the Reverse Upper Decker mug.Same as the standard upper decker except you eat a 20-pack of White Castles first and then take the massive dump in the tank. when the next poor slob flushes, the smell from the dirty water will cause an uncontrollable craving for White Castles.
When my ass was about to explode from that 20-pack of castles I ate, I gave marco's toilet a jersey upper decker.

Get the jersey upper decker mug.AN ACT OF WAR. To take shit shit (some crazy how) in the upper tank of a conventional toilet. The next flush will be your shit and shit colored water. WARNING: The tank will be saturated with your shit. Hence the WAR about to commence. Do not do this without an immediate exit plan. And a fucking follow up plan of how and why you did such a fucking nasty thing.
I took and Upper Decker and dipped. Because I hate that fuck. And I am also a nasty unhygienic piece of shit whom wanted to fowl their party and embarrass.... fucking however.
