Sans is the laid-back skeleton from Toby Fox's Undertale, released in 2015, and his short voice blips and laugh have become instantly recognisable to players and meme makers alike. Clipped, overdriven versions like this one circulate on soundboards and in short-form edits, where the familiar character sound is pushed until it breaks. That broken quality fits glitch humour, horror-tinged jokes and ironic reactions, which is why creators keep reaching for it long after Undertale's release.
