The Sunday before college starts where parents drive their station wagons up to the college to help their kids move in and prepare for college life. Station wagons are the only car they can fit all their kid's stuff in.
Billy: Do there seem to be an exponentially high amount of station wagons parked around campus today?

John: Yeah man, where have you been? School starts tomorrow... it's station-wagon Sunday.
