1.)a really large quantity of marijuana smoked at one time out of one smoking device.
2.)a stoner holiday that occurs every year on the same day as the lesser known Superbowl of the NFL. Much marijuana and munchies are consumed on this day. This day is generally accepted in the stoner community as just another excuse to consume large amounts of intoxicants.
An opportunity to stuff your face with snacks, deck yourself out in face paint while bellowing like a fratboy even though you're a thirteen-year-old girl, sounding more like a drunk trucker, and to listen to all the white rap songs about the packers.
Oh, and football. But who watches the Superbowl for football?
