Casper

A Casper is a freestyle stance where the skateboard is upside down and balanced on the point of the tail. The skater's back foot is on the underside of the tail and the board maintains its angled position by the skater's front foot being hooked under the deck. It is important to note that having the front foot on the floor is considered cheating, and not a proper casper.

On the other side, you could try to drop the front part of the board and then catch it with the front foot repeatedly, which is a real crowd-pleaser (because of the rhythm) and attention-grabber (because of the noise).
