The line comes from Pulp Fiction, Quentin Tarantino's 1994 crime film, in the apartment scene where hitman Jules Winnfield, played by Samuel L. Jackson, interrogates Brett and snaps when Brett stammers in panic. The full line in the film is longer and includes profanity, but this short cut isolates the question itself. Clips and screenshots from the scene have circulated for years as reaction memes for moments of confusion, and the trimmed audio became a popular soundboard staple because it works without any visual context.
