when spanish speakinq person is tryinq to say share.

An uncommon sexual position, where the willing or usually unwilling participant is strapped into a lawn chair (the conventional method is duct tape but varied uses have included rope, electrical cords and Christmas lights.) The person is then flipped upside down and a hole is cut out of the seat, exposing the person's anus and/or genitalia, creating a make-shift glory hole for instant gratification. Common practice is to "chair" outside but the more bashful often commence the activity in the garage or pool house.

almost always useful. a person has to invest a great amount of faith into this object, for if it breaks (which is entirely possible) then one is putting the fact that they are currently not disabled at great risk ie. they could become disabled

Something you sit on

The act of having someone sit on a chair blindfolded and have one or more persons dick slap the person sitting in the face. Can be done for pleasure or as a punishment.

Originating from Gossip Girl fans all around the world, the word Chair is basically a different version of the already defined Waldass. It's a combination of the two characters names, to make one.
So in other words;
Chuck + Blair = Chair

Got it? Good.
