"Parkour, a made-up word, cousin to the French parcours, which
means “route,” is a quasi commando system of leaps, vaults, rolls, and
landings designed to help a person avoid or surmount whatever lies in
his path—a vocabulary, that is, to be employed in finding one’s way
among obstacles. Parkour goes over walls, not around them; it takes the
stair rail, not the stairs." New Yorker
