'Enemy spotted' is one of the classic radio commands from the Counter-Strike series, dating back to the early 2000s when players used in-game radio to coordinate without voice chat. The short callout let teammates flag hostile contact instantly, and its clipped military delivery made it stick. As CS clips flooded video platforms, the line escaped the game and became a meme shorthand for noticing danger — or someone you'd rather avoid. Editors still use it to fake a tactical alert over everyday footage.
