It's when you take a couple ounces, a package of rolling papers, a 5-pack of Dutch Masters, duct tape, 15 people, and all the glass or Macgyver'd paraphernalia that those people own.
1. Get everyone and everything together.
2. Have people start rolling joints and blunts and/or Macgyvering some more paraphernalia.
3. You make an 8x8 grid on the carpet/tarp with the duct tape.
4. The biggest pieces/bongs are the kings/queens, then the bishops, knights and rooks in that order.
5. Pawns can be whatever, but by this point if you haven't used up the blunts they're either bowls or joints.
6. The two people who contributed the most amount of plant are team captains, and get to pick two others to help them out.
7. When a piece is taken, it is lit by the team that took it, passed to the other team, and then around the circle of spectators.
8. When the game is over, the winning team starts the remaining pieces and passes them again to the other team and around to the spectators.
9. Order 12 Pizzas and watch The Sword in the Stone.
Side note: we had a 2.5 foot homemade bong, two gravity bongs, 3 1-footers, a zong, 7 or 8 blunts, 6 bowls, 1 bubbler, and the rest joints. Afterwards we smoked some more (a friend of mine, who can be seen in one of the videos in the skateboard thread in ILF, had a quarter of Northern Lights) and just did whatever.
