Spiceymon
A game in which all participants play Pokemon on DS/Gameboys, the only rule being that players must take a hit of spice every time they save the game. Spice lending itself well to mind narrowing effects goes well with Pokemon. This game usually leads to a multiday spiceymon binge.
Johnathon has been playing spiceymon relentlessly for five days now. I think he has smoked 7 grams of spice since he started on monday.
