- (slang, law) To plead guilty to a lesser criminal charge than one had been charged with.
1958, Nelson Algren, A Walk on the Wild Side, page 312:
- But blow wise to this, buddy, blow wise to this: Never play cards with a man called Doc. Never eat at a place called Mom's. Never sleep with a woman whose troubles are worse than your own. Never let nobody talk you into shaking another man's jolt. And never you cop another man's plea. I've tried 'em all and I know. They don't work.
