GAMBIAN

Gambian is an African martial art that is a deep-seated tradition and national sport. The warriors wear loincloths called "Juju's" and strut, dance, spar, and brag in challenge of noisy support from the drums. The fight continues until a contestant is brought to the ground. Punching, kicking, spitting and flinging sand in the eyes is all legal. After sundown, the atmosphere builds with excitment as the champions come out to fight.
