knock (throw) for a loop. To hit someone or something very hard, to defeat, to astonish or upset. This Americanism has been traced back to the early 1920s. Loop may have originally referred to the loop maneuver made by an airplane, but that is only a guess. The expression has several colorful variations, in- cluding knock for a row of ashcans, knock for a row of milk cans, knock for a row of Chinese pagodas, and, best of all, knock for a row of tall red totem poles. |
