Is a prank that happens when one person is in the shower and another person enters the bathroom and takes a nasty shit in the toilet. By the time person number one is finished with their shower, a large amount of steam will have accumulated in the room. The smell from the toilet will then be stuck at the bottom layer of steam which conveniently is about face level. This makes it almost impossible to exit the bathroom without smelling person number 2's handywork.

A variation of a "Wet Willy" but where emphasis in the "Wet Willy" is placed upon saliva, the emphasis in the Steamboat variation is placed upon ass sweat.
