A Rusty Dusty is when someone lays on their shoulders with their anus facing upward (it helps to lean against a wall), then player 2 places an amount of their powdered drug of choice onto the anus of player 1. Next, player 2 takes a funnel and aims the wide end at player 1s anus while inserting the thin end into one nostril while covering the other. Once all participants are in position, player one releases the biggest fart they can possibly muster, sending a plume of powdered narcotics into the funnel which is then sucked into the nose of player 2.
