Stack

Stack is a slang term for $1,000, along with "grand," "g," and "band." The name comes from the idea of a stack of money, often imagined as a neat pile of dollar bills. While the term is commonly associated with U.S. currency, especially stacks of $100 bills called "Benjamins," people may use it casually to refer to large amounts of money in general.

The word became especially popular in hip-hop culture, where artists often reference stacks when talking about success, wealth, or ambition. In lyrics or conversation, saying someone "has a stack" usually means they have at least $1,000 or a noticeable amount of cash. You may also hear people talk about "stacking up," which means earning, saving, or accumulating more money.
