Got the purple drink,
Purple Drank is the slang term for a mixture codeine and promethazine. It is used by a lot of the rappers coming from Texas, especially Houston, which makes A$AP an odd case, because he hails from Harlem, but has that Houston flow. He pays tribute to Houston in the song Houston Old Head.
