faster than Minute Rice

(simile, US) very quickly, in a great hurry.

Quicker than scat is an American simile meaning extremely fast — done in an instant, gone before you could blink. Scat here refers to a sharp command to shoo or scatter animals, capturing the sudden bolt of something startled into motion. It's the kind of colorful folksy expression you'd hear in rural America, Southern vernacular, or from anyone who grew up using language that actually had some flavour to it. Use it when regular fast just doesn't cut it.

(simile, Scotland) Very stupid.

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.
