The acronym "FAFO" stands for "F*** Around and Find Out." It is a slang term used to warn that actions have consequences, particularly when someone behaves recklessly or provocatively and then experiences the resulting repercussions. The phrase is akin to sayings like "If you mess with the bull, you get the horns." It has gained popularity on social media platforms like TikTok and is used to express a tough, no-nonsense mindset, sometimes in political or military contexts as well.
