Risitas refers to Spanish comedian Juan Joya Borja, whose laughter during a television interview became a widely shared internet meme. The clip spread through edited reposts, subtitled versions, and reaction videos across forums, YouTube, and social media in the 2010s. It remains popular because the laugh is instantly recognizable and communicates disbelief, ridicule, and infectious amusement without needing much context. Online, it is often used alongside other exaggerated reaction sounds such as Nelson's HA-HA! or the laughing dog meme.
