When you have a massive deuce that must come out when your at a big party. You remove the top lid to the toilet, and release all the poo into it. When done, put the lid back on, and walk out like nothing happened.

Get the upper decker mug.Besides the common definition... A behemoth, often coiling, mass of stool that grows and grows until finally reaching above the water level of a toilet bowl. Known to be associated with binge eating. Kind of like one of those underwater volcanoes that breaks the ocean surface.
I had the munchies so bad all weekend, btw do you have a plunger I took an upper decker in your shitter and it's backed up.

Get the upper decker mug.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.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.
