The honk was created by sound designer Jimmy MacDonald for the Mickey Mouse cartoon Moving Day, released in 1936, when early animation relied on expressive, hand-made effects to carry jokes without dialogue. That brassy, comic style later became a staple of cartoon sound libraries, which is how the same honk reached later shows including The Grim Adventures of Billy and Mandy. Online, creators reuse it because it is instantly recognisable as old-school cartoon humour, short enough to drop into edits, and still funny when paired with modern fails and reactions.
