Grind (skateboarding)

In skateboarding, grinds are tricks that involve the skateboarder sliding along a surface, making contact with the trucks of the skateboard. Grinds can be performed on any object narrow enough to fit between wheels and are performed on curbs, rails, the coping of a skate ramp, funboxes, ledges, and a variety of other surfaces.

Grinds are typically categorized as either "frontside", where the rider approaches the feature with their front facing it, or "backside", where they approach with their back facing it.
