Politically, it has gained particular prominence in recent years and was notably used during the 2024 election and in geopolitical discussions, for instance by President Donald Trump and various public figures, signifying a tough stance or warning.
In brief, FAFO means "F*** Around and Find Out," warning that meddling or problematic behavior will lead to direct consequences.
