Military slang for a jet fighter or fast-attack aircraft — the kind of plane that screams overhead and disappears before you've even processed it. Used mostly in ground troop and aviation communications to distinguish supersonic jets from helicopters or prop planes. It captures the jaw-dropping speed differential in one punchy phrase. Civilians sometimes borrow it to describe anything moving at an insane clip — a stock, a career, a date who's already texting about a second outing.
The FAC called in a fast mover for close air support, and within minutes the whole ridge line was quiet.
