SKI Slopestyle: A style of competition held on a course that includes a variety of hits, jumps, rails, tables and big-airs, and which offers competitors two or more lines (descent routes) that the competitors may choose to perform. Skiers are judged on six criteria: execution, amplitude, variety, degree of difficulty, artistry and specific combinations.
- Amplitude: An element of an athletes score based on going big from takeoff to landing. The idea that a rider will come into a jump with speed, do their trick high in the air and finish deep on the landing track. The ideal picture would include a nice arc. The overall height and scope of the trick is factored into the amplitude score.
- Flip: Rotating over a vertical axis.
- Frontside/Backside: Spinning off a jump or onto a rail or box while opening (frontside) or closing (backside) ones chest to the landing.
- Left foot forward/Right foot forward: Describes which foot is leading, or is more downhill, when a skier jumps onto a rail. how the skier gets onto the rail. If they turn to the left jumping onto the rail, the trick would start with right foot forward, and vice versa.
- Left side/Right side: The direction a skier spins during a trick. If a skier goes off a jump and turns to the left, the name of the trick starts with left side, followed by how many spins or flips they perform.
- Lipslide: When a skier jumps into the air and rotates the tails of their skis over the rail before landing on it.
- Rotations (180/360/540/720/900/1080): The number of times a boarder spins on a horizontal axis either in the air or on a rail. A 180 (one eighty) = half a spin, 360 (three sixty) = one full spin, etc.
- Switch: Skiing backwards; describes a trick that begins with the tails of the skis pointing downhill.
- Frontside 450 out: Doing one and a half spins while opening ones chest downhill while jumping off a rail.
- Frontside 180 out to wall ride tranny: Rotating a half-turn with ones chest facing downhill while transitioning from a rail to a wall.
- Triple cork 1440: Going off a jump with ones tips facing downhill, and spinning three times (1440 degrees) while doing three full flips at the same time.
- Switch double misty 1260: With the tails of his/her skis pointing downhill, the skier goes off the jump and flips twice while spinning either three and a half times.
