A short clip like this spreads because it is easy to reuse: the phrase is familiar slang, the delivery is playful, and the whole sound lasts barely more than a second, so it fits neatly at the start of a meme, a reaction video or a gaming highlight. Without a clear single source, it has circulated as a generic greeting sound on soundboards and in short-form edits, where creators use it to signal a friend arriving, a joke beginning or a scene changing. Its simplicity is the point, and that keeps it useful long after any single trend fades.
