Gravity release, wind + wind (or earth).
Now you can shift wind and form it into gravity control with enough chakra control, and elemental recomposition.
I've became OBSESSED with gravity release or some type of law defying nature ever since Pein first used Almighty push. It would seem at first like he's basically turning himself into the center of a rasengan and making his chakra create a deadly fast spinning force of chakra, but you can see this isn't the fact, when he propells a character towards himself at dangerously high speeds, where this couldn't be done with he above theory.
