A game for stoners derived from the children's toy game Buckaroo! The first person to pass out from smoking too much weed becomes the monger. Everyone else is then to proceed with stacking random things or items from around the room on the monger. The aim of the game is to get as many items on the monger before he/she wakes up. It is rare to beat the monger, however, it has been done.
Last night Matt passed out and we actually beat him at a game of mongeroo.
