McDickered is a word of Canadian origin, describing the state of an individual of whom has partaken in some McDonalds, and all its glory, while being highly inebriated.
Another name for McDonald's, McDank's, or whatever the hell else you want to call that fast food chain that sells them Big Mickeys. Known for attracting some "big" clientele, as well as the uber hungry after everyone else hits the sack.
Pothead: "Me and Lenny decided to hit up McDickenheimer's after we smoked all our schwag. I almost crashed the station wagon on the way there."
