When one or more person plays "Russian Roulette" with a fully-loaded revolver and hoping (or not) it jams; because the revolver is so old and rusty.
Common nick-name; Grozny
Soldier: So what happened with the rebel leader again?
Officer: He heard he played Grozny Revolution with his friend.
Soldier: What does that mean?
Officer: You load a revolver fully and play Russian Roulette. Ironic right? They're guns are so old I wouldn't be surprised if they jam.
