The exact original source of this chant is not clearly documented, so it is best understood as a meme sound that circulates on soundboards rather than as a clip from a named film or show. Its published description is Boiboiboi, which matches the repeated vocal at its centre. That simplicity helped it travel as a reusable reaction, passed between creators who use the same chant to mark something absurd, playful or deliberately over the top. It remains in use because the sound is instantly recognisable, easy to place, and does not depend on knowing a specific reference to land.
