About this sound

✦ AI

A short Mettaton voice clip saying "Ohh yess" from Undertale, used in memes, reaction edits and dramatic reveal moments with extra flair.

This sound is a brief, theatrical voice line from Mettaton in Undertale: a drawn-out "Ohh yess" delivered with showy confidence. It has a smooth, campy tone that instantly makes a moment feel more dramatic, stylish or smug. Because the clip is so short and expressive, creators use it to punch up glow-ups, over-the-top entrances, approvals and joke reveals. Even without context, the performance sells attitude right away, which is why it works so well as a reaction sound in fast edits, gaming clips and meme posts.

This clip comes from Undertale, the 2015 indie RPG by Toby Fox, where Mettaton is one of the game's most theatrical characters. Short voice-like lines tied to memorable dialogue became popular outside the game as fans clipped them for reaction posts, edits and fandom memes. Mettaton's exaggerated delivery helped this line stick around, especially in posts that need instant drama or playful approval. It still gets used because the character is recognizable to many players and the line is short enough to fit almost any punchline.

Pro Tip for Usage

✦ AI

Place this right after a flashy reveal, outfit change or perfect comeback, then freeze for a beat on the reaction shot. It works best with dramatic zooms or sparkly edits, and less well if too many other voice clips overlap it.

Use Cases

✦ AI
  • Adding flair to a glow-up or makeover reveal.
  • Reacting to a dramatic entrance in gaming edits.
  • Punctuating a smug win or perfect comeback.
  • Underscoring over-the-top thirst or admiration jokes.
