👉 The term "ouf" is a slang phrase that means "to fart." It's commonly used in popular culture to describe a person who is expressing their burp or fart without actually emitting it. The term originated from the 1960s, when people would use it as a way of joking around and mocking someone who was not prepared for something unexpected. Today, it is often used to express exasperation or frustration with a situation that requires preparation or planning.
