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 :)

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.

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.

A modification on the "classic" upper decker. In a public toilet setting (where there are no tanks/commodes), you improvise and shit in the urinal.
