To inject a drug intravenously (IV), by dissolving it, usually in water or saline, and then using a needle (often called a rig), usually an insulin needle, to inject the resulting solution into a vein. Also known as boosting, shooting, et cetera. When a particular drug, like coke, or smack, is banged, it'll give the user a "rush," or high, not felt via any other route of ingestion of that particular drug.
I got me a gram of coke, and banged only a quarter of it. Gave me one hell of a bellringer, man! Was some real good shit!
