Definitions are, by definition, arbitrary. Nonetheless, some are more elegant and intuitive than others.

I came to boarding from the skiing world where there are exactly two ways to turn: 1) carving or traveling parallel to the length of the ski; or 2) skidding or moving at some sideways vector to the length of the board. In practical terms, virtually all ski (and snowboard) turns involve some combination of the two elements since a given board can only make an absolutely pure arc of the radius determined by the sidecut. All good ski racers predominantly carve because it is dramatically more efficient, and therefore faster.

In snowboard parlance, carving is apparently defined as "a not-skidding turn at high speed and edge angles." Aside from the inartfulness of defining the superior technique as the negative of the inferior, the snowboard definition confuses the discussion by introducing the extraneous factors of speed and edge angle. Surely the predominant concept that needs to be clearly communicated is the direction of travel of the board across the snow because that is the element that dictates the level of control and allows the least effort to produce the desired result. Speed and edge angle are mere refinements of the core concept.

So, for the snowboard purists, I really don't try to carve all of my turns. I simply do my best to create not-skidded turns at all speeds and edge angles.
