The line comes from Quentin Tarantino's 1994 film Pulp Fiction, in the early scene where Jules Winnfield interrogates Brett and loses patience with his nervous replies. Samuel L Jackson's delivery turned say what again I dare you into one of the film's most quoted moments. Clips and quote posts spread it across forums, video edits, and soundboards, where the isolated challenge became a shorthand reaction for disbelief and mock intimidation. Its lasting popularity comes from the performance remaining intense even when removed from the full scene.
