Carving - explained in the PalmerProject-Ski and Snowboard-Lexicon
Carving is when you ski a turn with very little skidding, using the edges of your skis.For most people, the ultimate goal of skiing is to be able to carve their turns perfectly. Carving is the word used to describe the way people ride boards - skateboards, snowboards and surfboards. While riding a board, the rider leans and cuts into turns, and this is called "carving". Most skate parks in the US are made with lots of "flow", meaning the concrete smoothly slopes in such a way that skaters can carve a line all over the park easily. The better flow a park has, the better carving the skaters can experience.
