This story about the US military misunderstanding the “friends of Dorothy” euphemism is sublime
In the early 1980s, the Naval Investigative Service was investigating homosexuality in the Chicago area. Agents discovered that gay men sometimes referred to themselves as “friends of Dorothy.”
Unaware of the historical meaning of the term, the NIS believed that there actually was some woman named Dorothy at the center of a massive ring of homosexual military personnel, so they launched an enormous and futile hunt for the elusive “Dorothy”, hoping to find her and convince her to reveal the names of gay servicemembers.
