Clips of his distinctive laugh began circulating as a standalone reaction sound across Spanish-speaking TikTok, Instagram and WhatsApp chats, where users repurposed it to mock boasts, fails and awkward moments. Because the laugh is instantly recognisable and needs no translation, it spread beyond his original audience and remains a popular shorthand for sarcastic amusement in short-form videos and meme edits.
