Shinner
Also known as: shin, shin hit
The classic crack of the board's edge into your shin when you blow a flip.
Extended definition
A shinner is that whack to the shin when the deck flips wrong and the edge comes straight up into your leg. It hurts like hell, leaves a textbook purple egg, and is a universal rite of passage while learning kickflips and ollies. It's part of the toll for learning to skate.
