The exact origin of the Wouahou clip is unknown, so it is best treated as a stock-style sound effect rather than a quote from a specific show or film. The spelling comes from the French onomatopoeia for a dog's bark, and clips like it circulate widely on soundboards, meme pages and short-form video editors as a handy one-second bark. Its appeal is practical: it is short, recognisable and instantly comic, which is why editors keep reusing it to add a playful canine accent to pranks, reaction videos and pet memes.
