A trick performed in a sport, such as skateboarding, moving along a cornered or thin surface in an unorthodox manner, usually without using the wheels.

Oddly, real-life skateboarders are impressive for grinding a few feet, while in most skateboarding video games, you can grind for half a mile without losing balance at all.

Short for "Grindcore."

Grindcore, or "grind" for short is a type of very fast speed/thrash metal, death metal, or hardcore punk or perhaps a combination of both(depending on how the band plays it). Grind is characterized by very fast drumming that makes predominant use of the blastbeat, very fast thrash metal-style guitar playing, growling/screaming vocals(much like in death metal), and usually rather short songs. The world's shortest song ever is "You Suffer," a grind song written and recorded by grind pioneers Napalm Death. This song only lasts 1 to 4 seconds and its lyrics are "You suffer. But why?"

And despite what many people may think, the British bands Napalm Death and Carcass did not really invent grind. Napalm Death named the genre. Grind is actually an American invention, started in the mid-eighties by Repulsion, a death metal band from Mississippi who wanted to create their own style of brutal music. In 1986, they've released the world's first full-length grind album, "Horrified." Their style of metal was later copied by bands such as Napalm Death and Carcass and the genre still goes on today, though it has never gotten to the mainstream. Still, it's much better than all the nu-metal crap that has plagued the music world since the mid-90s.
Types of grind:

Political grindcore (Napalm Death)
Goregrind (Repulsion, Carcass)
Pornogrind
Crust
Death/Grind (Grind with significant death metal influences)
