The path of a large, densely packed, unwieldy turd as it slides down the side of a toilet bowl, often resulting in a stubborn, hard-to-clean streak/smear that won't disappear with the waters of a standard flush.
Call in the reinforcements, there's been a major turdslide in here.
Jim Wilke, or any other IRL fan who is too dumb to even classify as a full turd. The word "turdslice" is used to describe an extremely dumb motherfucker without insulting the class of dumbfucks and dipshits.
