英语词汇bug out的起源、历史背景-英语词源词典

bug out; swanning. To bug out, “to retreat hastily,” is an ex- pression that dates back to the time of the Korean War, when it was first used by teenagers and then in the United Nations “po- lice action” to indicate a military retreat. Since retreats are generally the result of fear, the expression is another one that probably derives in a roundabout way from “bugaboo” or “bogey.” Incidentally, the migrating habits of the swan inspired the word swanning, “going purposefully anywhere without a purpose,” which meant the same thing that bugging out did during the Korean War. Today bug out is also slang for “freak out” or “flip out.”
