What is 3 sheets to the wind?

"Three sheets to the wind" is an idiomatic expression that means a person is extremely drunk or intoxicated. It was originally a maritime term used to describe a ship that lost control due to the wind taking the sails (sheets) and causing the ship to list uncontrollably.

The expression can also be traced back to the 19th century when sailors would use sheets as markers for how much alcohol they had consumed. A sailor who had consumed three sheets or more would be considered "three sheets to the wind."

In modern times, the expression is often used in informal settings to describe a person who is heavily intoxicated and unable to function properly due to the effects of alcohol or drugs. It can also be used humorously to describe someone who is acting in a silly or foolish way due to their level of intoxication.

Overall, "three sheets to the wind" is a colorful and evocative way to describe a state of extreme drunkenness that has its roots in maritime tradition.
