The razz comes from Canine Caddy, a Mickey Mouse cartoon released on 30 May 1941, where a brief jeering raspberry was used for comic disapproval. It was later preserved as a stock sound effect, catalogued as an angry razz by a small group of men, long after the cartoon faded from viewing. Online creators rediscovered that short, instantly readable jeer and began dropping it into memes, reaction videos, and short edits, where a fraction of a second is enough to signal mockery. Its age and cartoon origin give it a familiar, old-fashioned sting that still works today.
