Kiko is a character from El Chavo del Ocho, the Mexican sitcom created by Roberto Gómez Bolaños that became hugely popular across Latin America, where in Brazil it is known as Chaves. Played by Carlos Villagrán, Kiko is a spoiled, cheeky boy whose distinctive laugh became one of the show's most quoted sounds. Decades of reruns kept the character familiar to new generations, and short clips of his laugh later spread through YouTube, WhatsApp and TikTok edits, where Brazilian and Spanish-speaking creators use it as a quick, instantly understood reaction to mockery or silliness.
