This sound is a generic boat horn or foghorn style effect rather than a quote tied to one specific character or scene. Online, clips like this spread through meme edits, prank videos and short skits because the low repeated blasts instantly read as huge, dramatic and a little absurd. It fills a similar role to an air horn, but with a slower, heavier feel that suits ship jokes, grand entrances and intentionally overdone reaction moments. Its usefulness comes from how quickly listeners recognize the sound.
