Where you go to someone's house, shit in the tank part of the toilet. the shit in there starts rotting, and starts smelling up the bathroom, and people don't know where the smell is coming from because they never look in the tank part of the toilet.

I took a crap in CJ's Top Tank and left him a Upper Deck he will never forget.
