The Mackey Special

Leaving a duke (poop, turd, feces, etc) in a urinal.

Description of The Mackey Special:

Mr. Mackey: Oh, ya think that's funny, huh? Let me assure you, there is nothing funny about going up to a nice, clean, unsuspecting urinal, m'kay, dropping your pants, then turning around, squatting over that urinal, m'kay, maybe, maybe, pulling your butt cheeks apart with your hands, m'kay, and then laying out a big fudge dragon for all the world to see.
