fill the tank

To shit in the back tank of a toilet, after removing the cover. This is best done in a public bathroom, as the turd(s) will not likely be found for several weeks, despite the pure, rancid stank it will emit. Due to the general orientation of the toilet tank and the wall, this can be a difficult task, and any successful attempt should be properly commended.

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