The clip circulates online as a generic reaction sound rather than from a widely identified movie or show, and its exact origin is not clearly documented. Its popularity comes from how reusable the phrase is, since almost any video about quizzes, schoolwork, gaming mistakes or confident misinformation can use the same correction. Short voice reactions like this spread through soundboards and short-form edits, where creators reuse the line as an instant signal that an answer has failed, without needing the original context.
About this sound
A short clip of a man calmly saying that's not correct, used as a reaction sound for wrong answers, mistakes and awkward corrections online.
The sound is a brief, deadpan voice line where a man flatly states that something is not correct. There is no shouting or drama, just a calm, slightly dismissive correction delivered in a clear tone over about two seconds. That understated delivery is what makes it funny, because it turns a simple fact-check into a blunt put-down. Viewers instantly understand the moment as a fail or a bad take being shut down, which makes the clip work well as a quick punchline without needing any extra context or explanation to land.
