Three sheets to the wind
This phrase is often used to describe someone who is very drunk or intoxicated. The idiom originates from sailing. In the past, ships used to have three main sails, which were sometimes referred to as “sheets.” If these sails were not secured properly and were allowed to flap in the wind, the ship would sway and stagger much like a drunk person. So, when someone is described as “three sheets to the wind,” it means they are as unsteady and out of control as a ship with its sails in disarray.
When someone is three sheets to the wind, they are typically very intoxicated to the point of being unable to walk straight, speak clearly, or make coherent decisions. It’s a colorful way to describe someone who has had a bit too much to drink. So, next time you hear someone say that someone is “three sheets to the wind,” you’ll know they mean that person is really drunk and not in the best state to make sensible choices.
