Basically doing a handstand on skateboard. Many variations evolved from this, including One Handed Handstands, Headstands, Frogstands, Handstand Wheelies, Handstand Pivots, and handstand kickflips/fingerflips. The Handstand was taken to the other stances too such as Railstand Handstands, with the Single, Double, Varial and 360 Flips out of them, also TV Stands which are Handstands done in 50-50(Truckstand) stance.
