XDDD comes from Spanish speaking internet culture, where repeated D letters mimic a wide laughing grin in text, similar to LOL in English, and graciosísimo is an emphatic way of saying very funny. Short laugh reactions like this spread through WhatsApp groups, meme pages and short video edits because they need no context to understand. The clip stays popular as a ready made reaction for jokes, fails and awkward moments, especially in Spanish language chats where typing XDDD is already the default way to show you are laughing hard.
