green stamp

(slang) Money.

A cheerful, informal slang term for money — specifically cash, the physical kind. The name is a nod to the green color of US dollar bills, making it most natural in American contexts, though the term travels easily. It has an old-fashioned, slightly comic energy: the kind of phrase a character in a noir film might use when talking about a bribe or a poker pot. Today it appears in casual speech and lyrics when someone wants a slightly warmer, less clinical way to talk about cash.

The United States dollar.
