Bang Up
“(Whip.) Quite the thing, hellish fine. Well done. Compleat. Dashing. Ina handsome stile. A bang up cove; a dashing fellow who spends his money freely. To bang up prime: to bring your horses up in a dashing or fine style; as the swell’s rattler and prads are bang up prime; the gentleman sports an elegant carriage and fine horses.”
