An act performed by a young Jimmy McGill (aka Saul Goodman) on the TV show "Better Call Saul" which landed him behind bars. The specifics of this act are unknown, but it led to him being charged with assault, destruction of property, and a possible sex offense. Though Jimmy appears to think that a Chicago Sunroof is a harmless prank, the authorities believe otherwise.

Me and Jimmy went out and pulled a Chicago sunroof on that bitch Jackie's Hyundai. She'll never steal my parking space again!

A variant of the Chicago Sunroof where instead of defecating through a sunroof, you pour a tub of piss through a sunroof.
