About this sound
Mettaton's drawn-out Ohhh Yesss from Undertale, delivered in his dramatic showman voice for hype moments, wins and over-the-top excitement in memes.
This clip captures Mettaton, the flamboyant robot showman from Undertale, letting out a long, theatrical Ohhh yesss in his smooth, confident voice. The delivery starts low and teasing before rising into a satisfied, almost purring yes, stretched just long enough to feel deliberately dramatic. It sounds like a game-show host savoring applause, equal parts smug, flirtatious and gleefully self-aware. Played over a win, a reveal or a character finally getting what they wanted, it instantly signals approval and over-the-top delight, turning a small moment into a performance and making the audience feel in on the joke.
