Lil Jon, the Atlanta rapper and producer who helped popularise crunk in the early 2000s, became as famous for his shouted ad libs as for his music. Okay, alongside Yeah and What, turned into a signature catchphrase repeated across songs, interviews and television appearances, and was widely imitated in comedy sketches of the era. Online, the isolated shout was clipped for soundboards and meme edits, where its short length and unmistakable delivery made it reusable as an instant agreement or hype reaction long after the original tracks.
