Russian roulette

1.

An act of bravado played by loading one bullet into one chamber of a revolver in which the cylinder has five or six positions, spinning the cylinder (thus moving the bullet randomly to one of the six positions of the cylinder), pointing the gun to one's head, and pulling the trigger. If the bullet is in firing position, the "player" is usually killed. Such a "game" may be played on a dare, or, in some places, as part of a gamble.
