Drug dealing is a cryptic presence in cocaine rap, alluded to by dozens of synonyms and euphemisms but rarely by name. Many listeners will grasp the meaning of “snow.” (Young Jeezy’s nickname is the Snowman. When his logo, three stacked spheres, began appearing on high schoolers’ T-shirts last year, anti-drug groups complained and school districts banned the shirts.) But what about “keys” (kilos of cocaine); “trap house” (a place where cocaine is cooked into crack); “fishscale” (uncut cocaine); “triple beam” (a scale used to weigh the drug); “work,” “weight,” and “birds” (terms for parcels of cocaine)? In these songs, bricks, squares, **pies**, stones, and yams are **coke**, and the cooking, mixing, and weighing required to prepare the drug for clients becomes the inspiration for often inscrutable wordplay. As the Thorntons rap on a track called “Wamp Wamp,” “Mildewish, I heat it, it turns gluish. It cools to a tight wad; the Pyrex is Jewish. I get paper, it seems I get foolish. Take it to Jacob and play, ‘Which hue’s the bluest?’ ”
