The exact origin of the 'uokei' clip is undocumented, which is common for the shortest meme sounds that bounce between soundboards, group chats and short-form video edits. At under a second long, it belongs to the family of micro-reactions that creators keep on hand for quick punchlines rather than full quotes. Its appeal is pure utility: a funny, emphatic way to say okay without slowing the edit down. That simplicity is why tiny clips like this keep getting reused long after their source is forgotten.
