A trip taken from midnight until the time breakfast starts at McDonald's.
To start you must cross at a State line... and then go to as many McDonalds' as possible, while spending only 1 dollar per person at each McDonald's.
Its traditionally done on a Sunday, so that you can tell your buddies at school or workplace what happened.
NOTE: You cannot be either stoned, nor have the munchies, this negates the trip.
Todd and Steven went on a McQuest on Sunday, it was so epic, but so retarded at the same time. It was so gay... but so not gay at the same time.
