A highly anticipated board game that crosses the very definition of sanity. Most often used when under the influence of LSD, heroine, ecstasy, cocaine or a combination of the four.

The game, created by Imagination Games (a multi platform game company), leads you to perform a series of unordinary tasks that one would never consider doing in any sober state. It is not uncommon for players to quit the game after the first few rounds due to confusion, embarrassment, or drug overdose. A recent study at University of Maryland suggests that students tend to score worse on the SAT’s and other standardized tests after playing this game. Although nothing has yet to be proven, rumors have been circulating that Quelf is one of the underlying factors responsible for the poverty in South Africa, the current economic decline, and the H1N1 virus.
Hey man, I just picked up this new board game at Target called Quelf, do you want to play?

I would, but I'm getting drug tested at my current job. Next time I shoot up I'll let you know and we can play.
