Off axis rotation. Not a flip, not flat. And by off-axis, it is implied that the "axis" is an orthogonal set perpendicular in one dimension and parallel in the other to the direction of gravity.
Edit, that's not really clear I guess. Basically, a spin where you rotating not around your waist or over your head. The least corked spins literally look like a corkscrew ... imagine spinning around through the air and creating a helix with your shoulders. Corks have become so "corked" that they sometimes are closer to like an underflip but are still off-axis.
