The story
Pick-up basketball slang popularized (but not first coined) by Manute Bol, a basketball player of Sudanese origin playing with the Golden State Warriors, and subsequently adopted by teammates. Compare semantics with Russian оплошность (oplošnostʹ, “mistake, bad”), from о- (o-) + плох (plox, “bad”).
