A group of people stand in a circle. One of them fires an arrow upward into the air. Whoever stays in the circle the longest is the winner.
This is a dangerous game because the arrow could fall and hit the winner, or go out of control and hit one of the people who bailed.

Signing up for shared housing sight unseen, especially in a college or university setting. You may be assigned a roomate from hell or you may get someone pretty sweet. Many feel the risk is too high so they seek alternative housing sources. Term derived from the game Russian Roulette where a bullet is placed in the chamber of a revolver and placed up to ones head. You may luck out, but most dont think its worth the risk.
"Fuck that shit, last time I got assigned a roomate, he was an anal-retentive dork who played Halo all day and cock-blocked left and right. I ain't going to play roommate roulette this year, I am going to money up and get a studio."

A game that you are forced to play while studying at Copenhagen Business School.

Takes place whenever you're in the need of toilet facilities and are
a) entering a booth or
b) raising a toilet seat cover.

You loose in CBS-roulette if the toilet is blocked and full of yuk.

The chances for loosing in CBS-roulette are usually lower in the morning, and increases for every opening hour. In extreme cases the odds for loosing are close to 9/10.
A: Hey girl. You'll keep the table for us, while I'm getting some lunch?
B: Agh. Fuck it. You can have my lunch bag. I was suppose to take a quick wee before I met you, but lost CBS-roulette 7 times, and now I'm too disgraced to eat my lunch.

Getting in, she immediately found herself trapped in a stalled elevator in which some odious person had just played elevator roulette. She gagged as her eyes began to water, the overpowering stench permeating her freshly shampooed hair and the expensive silk blouse she had just had drycleaned.
