This is a casper flip.
A Casper flip is when you slide your foot up the board and at the same time you do a half kickflip.
Your back foot spins the board around your front foot and you land.
If you don’t land straight and you land side ways you will properly fall.
The video is good because it slows it down, so you get a good idea of what it looks like.
Casper flips are street tricks are really cool, when there sped up.
