This honk is listed as coming from Foul Hunting, a Goofy cartoon released on 31 October 1947, where that kind of rubber bulb horn was a staple of slapstick sound design. Short, instantly recognisable cartoon effects like this were later collected into professional sound libraries, including the Hollywood Edge catalogue, which helped them circulate far beyond their original film. Today creators reuse the clip as a quick comedic accent, because its vintage cartoon character needs no explanation and works in memes, edits and short videos.
