The 'nyeh heh heh' laugh is best known as the signature chuckle of Papyrus, the loud and lovable skeleton from Toby Fox's 2015 role-playing game Undertale, where the line appears as on-screen text during his boastful speeches. Fans adopted it as shorthand for theatrical overconfidence, and it spread through memes, animations and impression videos across YouTube and TikTok. This particular clip is a fan-made vocal imitation, the kind users record for soundboards, and it sits naturally alongside other goofy laugh clips like the baby laughing meme and the cat laugh meme.
