Upper Decker

Chicago slang for whipping out the rumpus maximus, doing a fruity little dance with your tooter, and shitting on one's roof.

Guy 1: he did an upper decker on my roof.
Guy 2: ewww man gross. Give him a Chicago sunroof
Guy 1: yeah I will, gotta get my gut going first though. Wanna get some deep dish pizza?
