fill the tank

To shit in the back tank of the toilet after removing the cover. This is best done in a public bathroom as it may not be discovered for weeks, despite the pure, rancid stank it will emit. Due to the orientation of the toilet to the wall, this task is often difficult, and any successful attempt should be properly commended.

Stephon: Any needledick can shit on the floor; it takes skill and grace to fill the tank.

Fortunately, he "went in the tank", so I knew my hand was good.
