Hophead
-
A drug user or addict. Hophead is an umbrella term for users of everything from cocaine to marijuana (or tea - which is a jazz era term, not one that originated with the Beats as is erroneously noted elsewhere @ the Urban Dictionary) to benzedrine (aka bennies/amphetamine). The term sprang from the early jazz scene in 1920s/30s America.
Decades later, beer aficionados appropriated the term to refer to themselves (with a wry tip of the hat to its original meaning).
