The greatest variant of basketball ever played. Played in the dark with little lighting with a black basketball (because any other color basketball is easier to see), to increase the risk of injury. Any basketball game can be used, but the best game to be played in these conditions is "21" or "tip-in", because it's widely considered to be the most violent of all basketball games.
Dan: Man, I feel like playing basketball and risking my life at the same time.
Brian: Perfect! Let's play black basketball!
