The clip comes from YouTube Rewind 2018, the year end video where Will Smith delivers the line it's rewind time with an exaggerated yaaaah at the start. That edition became one of the most talked about and disliked uploads on the platform, which turned his enthusiastic delivery into a lasting meme detached from the original video. The isolated yell circulated on soundboards and in short edits as a shorthand for hype, nostalgia and ironic celebration, and it remains recognised even by viewers who never watched the full Rewind.
