The sound comes from The Worm Turns, a Mickey Mouse cartoon released in 1937, where exaggerated cartoon horns were part of the era's slapstick sound design. Hollywood Edge later catalogued a similar musical car horn effect, which helped the short awooga burst circulate as a reusable stock effect beyond its original cartoon. It has survived because the sound is instantly recognisable as old-school comedy, even without any picture, and it still signals attraction, shock or a comic double take in memes and short videos today.
