Little is documented about where Gulugulu first came from, so it circulates mainly as a standalone reaction clip shared between soundboards and short video edits. It is often searched as gululu meme, a slightly different spelling that still leads people to the same gulping joke. The clip spread because it is short, recognisable and easy to drop over almost any face or drinking shot without any setup. That simplicity has kept it in regular use for nervous reactions, cartoon swallowing gags and quick meme punchlines long after similar novelty sounds have faded from feeds.
