Sonido Burla is a Spanish-language reaction sound that circulates on soundboards, messaging apps and short-video platforms, where its name simply describes its purpose as a sound for mocking or teasing. It is commonly used by Spanish-speaking creators to punctuate fails, awkward replies and playful insults, in the same way English-speaking meme makers use Nelson's HA-HA or a laughing dog meme. Because the laugh is short, clear and instantly recognisable, it travels easily between chats, edits and reaction videos, and it remains popular as a quick way to turn a mistake into a joke without needing any dialogue.
