revolving credit

The "extra chance" or "new lease on life" that you get each time the revolver clicks harmlessly on an empty chamber when playing Russian roulette.

Revolving credit only works for so long, and then you eventually get hit by the door on your way through --- that really happened, y' know --- a revolving door actually "pancaked" and smashed someone between the shattered glass panels! You can look up "Freak Accident With Glass Revolving Door" on YouTube.
