To everyone saying it's not a triple cork:
Skiing and snowboarding have different definitions for corks and rodeos. In snowboarding, any flip + spin trick is either a cork or a rodeo, doesn't matter if you do a full flip or an off-axis rotation. And most of the time if you don't go inverted very far, it's just called a spin. Unlike skiing, where it's called a cork when you go the tiniest bit off-axis, and an underflip when you do a complete flip.
Our corks are comparable to your underflips, and our rodeos to your flatspins.
So in snowboarding terms, this is a frontside triple cork 1440, and definitely not a triple rodeo or backflip.
