There is no widely confirmed mainstream origin attached to this specific Booyooy clip from the available information, so it is best understood as a short internet sound effect used for comedic timing. Sounds like this spread through reposted edits, meme compilations and short-form videos where creators need a quick audio cue for a strange or offbeat beat. Its staying power comes from how flexible it is: it can fill the same role as a vine boom, but with a lighter and sillier tone.
