Russian roulette

Etymology
From roulette, a game of chance involving a revolving wheel. The first description is apparently in "The Fatalist," an 1840 short story by Russian writer Mikhail Lermontov.

Proper noun

 * 1)  A deadly game in which a person loads a single bullet in the cylinder of a revolver, spins the cylinder so that the bullet's location is unknown, points the muzzle at his/her head, and pulls the trigger.
