friend of dorothy
What does friend of dorothy mean?
A discreet code for a gay man, used when being out could get you arrested or worse. Asking 'are you a friend of Dorothy?' was a way to quietly find your people without saying the dangerous part out loud. It traces to Judy Garland — gay icon, and Dorothy in The Wizard of Oz — though some point to the writer Dorothy Parker. The term dates back at least to World War II.
Origin
Mid-20th-century coded gay slang, tied to Judy Garland (Dorothy in The Wizard of Oz, a gay icon); in use by at least WWII.
