The exact source of this sound is not clear from the available information, but it is widely used online as a short vocal meme for teasing, bait-and-switch edits, and light mockery. Its repeated phrasing makes it easy to recognize even in very short clips, which helps it travel well in reposts and compilations. Like goofy ahh sounds, it sticks because the rhythm itself is funny. Creators keep using it when they want a joke to feel cheeky rather than aggressive, especially in fast reaction edits.
