When I was in middle school, I remember seeing graffiti around the school (carved into desks, written on bathroom walls, etc.) that looked like this:
(The ******* represents a sequence of three numbers I can no longer recall.)
Another kid in my class explained to me that those were the numbers representing Sex (69), Drugs (?), and Rock & Roll (2112). Now Sex = 69, I understand. Rock & Roll being 2112 is a stretch, presumably referring to the Rush album of that title (or does reference to 2112 predate Rush’s record?).
So what three-digit number stood for Drugs? Was it a police code, or something – analogous to the police code “187” becoming slang for “murder”?
