macaroni and cheese
n.— «While the mixture of heroin and Tylenol PM appears to be new, the moniker “cheese” is not. Drug dealers and users have long used the term for heroin and other drugs. For example, “macaroni and cheese” is slang for a $10 bag of cocaine and a $5 bag of marijuana.» —“New drug craze hits DISD” by Kent Fischer, Jason Trahan Dallas Morning News (Texas) Apr. 28, 2006.
