Casper Slide

A casper slide is a skateboarding flat ground or freestyle trick performed by flipping the board into an up-side down state with one foot on the bottom (now top) of the tail and the front foot underneath the front truck (griptape side) and sustaining momentum, thus sliding on the tip of the board's concave. It can be performed on rails (rarely done) or flat ground. A 360 spin on the board is done and even sometimes a 360 flip is performed. It is often attributed to Rodney Mullen.
