Doobie

American slang for a marijuana cigarette, first recorded in the late 1960s — the College Slang Research Project cites 1968, and Merriam-Webster notes origin "unknown." ⚠️ Etymology heavily disputed: proposed sources include the children's show Romper Room's "Do Bee" character (1950s–1960s), the adjective dubious, 1950s African-American jazz-musician argot, and biker subculture. The Doobie Brothers (formed 1970) adopted rather than coined the word. Chiefly U.S. counterculture vocabulary; persistent in print-media headlines as a family-friendly synonym.
