A short 'Oh, yes' voice clip from Undertale, commonly used as a cheeky reaction meme for dramatic reveals, smug moments, or playful approval.
This clip is a quick, theatrical 'Oh, yes' from Undertale, delivered with a drawn-out, confident tone that makes it instantly feel smug and dramatic. It is the kind of reaction sound people add when a joke lands, a reveal gets extra flair, or someone wants to act overly pleased with themselves. Even though it is only a little over a second long, the voice has a polished, showy attitude that gives edits a playful wink and makes ordinary moments feel intentionally overperformed.
This sound is associated with Undertale, the 2015 indie RPG by Toby Fox, and is widely recognized by players as part of Mettaton's flamboyant style. Short voice reactions from the game spread through meme edits, fandom videos, and gaming compilations because they are easy to place on a punchline. This clip remains popular since it delivers instant theatrical approval in barely more than a second, making it useful for ironic confidence, campy reveals, and exaggerated reaction posts.
