If you are very drunk, you may be "three sheets to the wind." The phrase comes from having a ship's sails properly fastened.
如果你喝得酩酊大醉，也許你就成了“三條風中凌亂的帆繩”（three sheets to the wind）。這一習語來自于適度拉緊的船帆。

According to researchers, "sheets" refer to the ropes that fasten a sail. If one of your sheets isn't properly tied down, the ship would become difficult to control and would be "to the wind," or moving erratically.
研究者稱，sheets指的是固定船帆的繩索。一旦一條繩索沒有綁緊，船便會變得難以控制，隨風行駛，或者飄搖不定。
