Retard rap

A sub-genre of rap usually characterized by overly repetitive song structure, unintelligible lyrics, obnoxious melodies, and excessive posturing and label-flashing by the artist.

A classic example of this would be "Crank That" by Soulja Boy.

Nick: Could you distinguish a single English word in the song we just heard?
Mike: Hell no, but what can you expect? It's retard rap.
