"Funny money" is a slang term that refers to counterfeit currency or fake money that is made to look like real currency. It is often used to describe any form of money that is not legitimate or has questionable value. This term can also apply to money that is obtained through illegal means or is not backed by a stable financial system. In a broader context, "funny money" can also refer to inflated or unrealistic financial figures, such as exaggerated profits or valuations in business. This usage highlights the idea that the money or financial claims may not hold true value, similar to how counterfeit money lacks authenticity.
