My paddle out take off pitched me into a screaming bottom turn that I roller coastered into a floating roundhouse cutback, then the wave started gorking and I pulled into the green room, there I saw the finish move, I charged the lip and pulled off a vertical tail slash ending with a double pirouetting cartwheel. As in any sport, terminology is the key to expression and understanding. Knowledge is the key to execution, and demonstration is the principal expression of skill.
Expertise comes with practice and practice starts with terminology.
The successful obtainment of a wave face. Radical change of surf direction or 'cut' on the face of a wave of at least 45 degrees, achieved by either turning towards or away from the wave peak. The craft pearls and stands on end than continues to fall forward. A 180 degree pirouette will allow the craft to remain surfing. A fluid continuation into a back endo with a half twist will combine into a Double Pirouetting Cartwheel.
