Swing through: the transition in which you land on one leg, the other leg ‘swings through’ without touching the ground, and you jump off of the initial leg you landed on. 

Swing throughs are typically used from the complete and semi landing stances.

There are two types of swing throughs, front swing and back swing.

A cork can utilize a back swing through

A raiz can utilize a front swing through

The top example is a back swing through

the bottom is a front swing

Pop: The transition in which you land on one leg, then the second, and then jump off of both legs. A pop that lands with both legs at the same time, but also has a long pause with a deep squat before the jump is still considered a pop.

Vanish/Tak: The transition in which you land on one leg, the second leg touches the ground, the first initial leg lifts up, and you jump off of only the second leg. This transition incorporates technique from the beginning of a ‘pop’ and the takeoff of a ‘wrap’.

Vanish applies to vertical kicks and various setups. A tornado kick uses a vanish to begin the trick, but you can also vanish into a raiz

Tak fulls use a vanish transition, but only apply to flips.

The tak full equivalent of a cheat900 would be a tak full round

The top 2 are examples of Vanish

This here is an example of tak (still uses a vanish)
