This quote comes from Pulp Fiction, the 1994 film directed by Quentin Tarantino. In the scene, Jules Winnfield, played by Samuel L. Jackson, uses the line during an intimidating exchange that made it one of the movie's most remembered bits of dialogue. Online, the clip spread through reaction videos, caption memes, and short edits because it works as an instant way to mock confusion or demand a clear answer. Its staying power comes from the delivery: brief, recognizable, and easy to drop into almost any argument joke.
