英语词汇pipe down的起源、历史背景-英语词源词典

pipe down. Pipe down began life as a dismissal command given a ship’s crew to go below decks after a task was completed or a formation had ended. This command was transmitted by the bos’n’s pipe or whistle, on which the bos’n could sound notes representing many orders. Pipe down came in the late 19th century to mean “shut up,” because it got much quieter on deck when the crew obeyed the order to go below and because the phrase pipe down itself suggested someone piping down or making less noise.
