This meme sound is known online as a short "feliz jueves" greeting and is especially tied to Asuka posts and anime meme culture. The exact original upload source is not clear from the available information, but the clip spread through reposts, soundboards, and social shares where people used it for weekly Thursday jokes. Its staying power comes from how quickly it delivers the joke: a simple Spanish greeting, a familiar anime association, and an easy format that people can reuse every week without much setup.
