The line comes from Half Baked, the 1998 stoner comedy co-written by and starring Dave Chappelle, where his character delivers the booing call as a comic put-down. Clipped from the film, it circulated on soundboards and social media as a short reaction sound for mocking unpopular opinions and embarrassing moments. Its simple, repeatable wording and Chappelle's recognisable delivery helped it travel beyond the film, and it remains popular in memes, gaming clips and reaction edits because it instantly frames someone as the butt of the joke.
