The original speaker and recording source of this short Spanish clip are not reliably documented. Online, it functions as a reusable reaction audio built around a familiar expression meaning that someone should not be such a liar. Its brief duration makes it easy to place after questionable claims in memes, short videos, chats, and edited conversations. The sound remains useful because the message is understood immediately by Spanish speakers, while the pointed delivery turns ordinary disbelief into a memorable comic response.
