Rackhorse Charlie

“Rackhorse Charlie” (also known as “Racehorse Charlie”) came to be a slang term from the 1930’s now specifically known for the drug cocaine. In modern drug slang, “C” is one of the well-known references used for describing cocaine. The term “Racehorse” implies something fast, strong, high performance (speed, power) — attributes users might metaphorically apply to a stimulant like cocaine, or to a powerful narcotic.
The use of the word “Rackhorse Charlie” is primarily implied in scenarios where you wouldn’t want anybody to know that you’re using cocaine.

“Hey, you wanna come over to my place later and get down with some Rackhorse Charlie.”
