Sans is the laid-back skeleton from Toby Fox's Undertale, released in 2015, and his deadpan humour made him one of the game's most quoted characters. Short clips of his voice and reactions spread through YouTube edits, TikTok videos and meme soundboards, where a single exaggerated scream became shorthand for sudden panic. Because Sans is instantly recognisable to gaming audiences, the sound still works years later as a quick, funny reaction without needing any context from the game itself.
