Ollie Sex Change
The Sex Change is a basic skill that skaters usually learn pretty early on in their skateboarding.
This is considered to be a street trick but it can be done on ramps too.
This trick is the same thing as a body varial.
The skater spins their body 180 while the board stays straight.
Take all that and throw an ollie in the mix and you have your Ollie Sex Change.
When skater think of sex change it is usually in reference to a kick flip body varial.
