“How about you? Are you a friend of Dorothy?”
A code adopted by gay men and LGBTQ+ individuals in general to subtly disclose your identity to another, “friend of Dorothy” is widely considered to originate with Judy Garland.
Judy Garland (born Frances Ethel Gumm) was an actress and singer most famous for The Wizard of Oz (1939) but starred in many other successful films such as Meet Me in St. Louis (1944) and A Star Is Born (1954).
Garland is adored by the LGBTQ+ community for this phrase, her human rights advocacy, her connection to the Stonewall Riots, and her history as a gay icon.
And the strong possibility that she was queer herself.
