The clip comes from a reaction-style recording in which a man vents his frustration at Sans, the famously difficult boss from the game Undertale, and the moment has since circulated as a short scream meme. Its appeal is simple: the extended shout is instantly recognisable as pure rage, so editors reuse it whenever a video needs an exaggerated reaction to defeat, bad luck or an unfair boss fight. Because Undertale remains widely played and quoted online, the sound keeps finding new audiences in gaming edits, reaction videos and short-form clips.
