Kiko, played by Carlos Villagrán, is one of the best-known characters from El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became a huge hit across Latin America in the 1970s and later in Brazil as Chaves. His high-pitched, childlike laugh became one of his trademarks, instantly recognisable even in a clip lasting less than a second. Fans began sharing short audio snippets of the laugh on soundboards, social media and WhatsApp, using it as a quick reaction to jokes and silly moments. Its brevity and familiarity keep it useful for fast meme edits today.
