Vitas is a Latvian singer who became an early internet sensation for his unusually high vocal range and theatrical stage presence, with clips of his performances circulating widely on video platforms and social media. As those performances were remixed into memes, his distinctive laugh became a shorthand reaction sound in its own right, easy to recognise even out of context. It remains popular because it is short, expressive, and instantly signals exaggerated amusement without needing dialogue or explanation.
