The line comes from SpongeBob SquarePants, the long-running Nickelodeon cartoon centred on Bikini Bottom, where Patrick Star is SpongeBob's dim but loyal best friend. Fans clipped Patrick's unusually formal greeting and shared it as a standalone reaction sound, separate from the episode around it. Online it spread through meme edits, streams and soundboards because the wording sounds like a proper valet while the voice is unmistakably Patrick. It remains popular for jokes about over-polite greetings, bad customer service and friends acting fancy for no reason.
