The chant comes from Half Baked, the 1998 stoner comedy starring Dave Chappelle, and was lifted from a scene where an audience rejects a speaker. Clipped from the film, the short booing moment spread through soundboards and reaction videos as a shorthand for rejecting a bad opinion. Because the delivery is playful rather than hostile, creators kept reusing it for sports fails, gaming moments, and political gaffes, and the better quality version helped it stay clear and punchy when layered over other audio.
