three sheets in the wind

slang Extremely drunk, especially to the point of being uncoordinated or out of control. Most likely derived from nautical terminology, in which a "sheet" is the rope that controls the sails of a tall ship; if several sheets are loose or mishandled, the boat's movement becomes unsteady and difficult to control, like that of a drunk person. On his 21st birthday, Jeff's friends took him to every bar in town until he was three sheets in the wind. They had an open bar at the staff party, so we were all three sheets in the wind by the time we left.

three sheets in/to the wind

Drunk. The term comes from sailing ships and refers to the sheet, or rope, that controls the sail. If a sheet is allowed to flap freely in the wind, the sail also flaps about and the vessel proceeds on a tottering course, like that of an intoxicated person. The more sheets are loose, the shakier the course. Dickens used the expression figuratively in Dombey and Son (1848): “Captain Cuttle, looking . . . at Bunsby more attentively, perceived that he was three sheets in the wind, or in plain words, drunk.” The expression may be obsolescent today, at least in America.
