Expressing a physical art such as skateboarding in an excessively stylish manor. Derived from the English Gnarly meaning "Quite dandy" and the English suffixes dog shred meaning “to finely dice an animal that is larger than a cat yet smaller than a horse." *Note* The word's emphasis is largely expanded if surrounded by "cash-money" signs as shown in the example bellow. Do not become bamboozled, "Nardogshred" is not a widely accepted currency! Although acceptations are made if Rad Percy is taking up residence in your neck of the woods.
A male usually a skateboarder/snowboarder who has past the height of his youth, but shows no remorse or value for the safety of his body. Gnardoggs usually sport facial hair, plaid western shirts, brown corduroy pants, and a beanie. They drink a lot, smoke a lot, and live hard.
Yo! Check that gnardogg down that 40oz then pummel that pool like it's nothing. He just got coping man! GNARRR
