The clip comes from Crank That (Soulja Boy), the 2007 breakout single by American rapper Soulja Boy that topped the Billboard Hot 100 and spread through its simple dance and online sharing. The opening youuu became the track signature call, quoted and imitated long after the dance faded. As short form video and soundboards grew, editors isolated that one shout from the intro and reused it as a standalone hype and reaction sound, separate from the full song, which is why it still appears in edits today.
