The line comes from The Last Dragon, the 1985 martial arts comedy film produced by Motown founder Berry Gordy. In the movie, Harlem martial artist Leroy Green searches for a master to complete his training, while the flamboyant villain Sho'nuff, played by Julius Carry, insists he is the master himself. His repeated question became the film's most quoted moment. Clips of the scene circulated for years in hip hop samples, wrestling promos and online edits, keeping the sound alive as a shorthand for bragging and playful rivalry.
