This clip is mainly known online as a reaction sound rather than for a clearly documented single source. It spread through short-form meme edits, reposted reaction compilations and TikTok-style videos where creators needed an exaggerated line for confusion or disbelief. Its popularity comes from how readable the emotion is in a fraction of a second. It often appears in the same kind of edits as other shocked reaction sounds, including a simple shocking cue, because both quickly underline that something on screen has gone completely off the rails.
