Vert is a term used in extreme sports especially vert skating, vert skateboarding, snowboarding and BMX to denote a competition held on a vert ramp which allows the competitors to fly into the air and land back on the ramp. This time in the air allows the competitor to perform moves which would otherwise be extremely difficult. An example of this would be a flip, or a spin. The term itself comes from the word "vertical," the direction in which the competitor is moving after leaving the ramp. Ramps used in these events are usually vert ramps.
