what does fafo stand for in the military

In the military context, FAFO stands for "F*** Around and Find Out." It is an internet slang acronym that serves as a warning that careless or provocative behavior will lead to consequences. The phrase gained recent popularity when U.S. Defense Secretary Pete Hegseth used it in remarks to military leaders, implying a tough stance against enemies who challenge the U.S. military. A softer alternative to the phrase is "Fool Around and Find Out." This acronym is used to signal a no-nonsense message of deterrence and consequences for adversaries, reflecting a confident and aggressive posture in military communication.
