The acronym "FAFO" stands for "F*** Around and Find Out." It is internet slang used as a warning that actions, especially provocative or careless ones, will have consequences. Essentially, it means if someone messes around or causes trouble, they will eventually face the results of those actions. This phrase is similar to sayings like "If you mess with the bull, you get the horns." It has grown popular on social media platforms like TikTok and has been used in both casual and political contexts recently, including by notable figures such as Donald Trump and Pete Hegseth. The term originates from African American Vernacular English (AAVE) and has been around since at least 2007 but has seen a surge in usage lately.
