NF, the American rapper known for intense, technically precise delivery, released That's a Joke as part of his wider catalogue of high-energy tracks built around personal pressure and defiance. The short clip circulates on soundboards because its title phrase and driving production translate easily outside the full song, letting editors borrow its confrontational tone without needing the surrounding verses. It remains popular in short-form edits and reaction clips, where a recognisable rap snippet can instantly frame a joke, a twist, or a confident response.
