In Brazil, Rabugento is the name given to Muttley, the snickering dog sidekick from Hanna-Barbera's Wacky Races, first broadcast in 1968 and known locally as Corrida Maluca. His wheezy, mocking laugh became one of the cartoon's most recognisable sounds, repeated whenever a scheme collapsed or his owner was frustrated. Clips of that laugh later circulated on Brazilian soundboards and messaging apps under the name Cachorro Rabujento, turning a classic cartoon cue into a quick reaction sound for teasing, failed plans, and grumpy pet jokes online today.
