This sound is best understood as a reusable internet fart effect rather than a quote tied to one famous character or scene. Clips like this spread through meme edits, prank videos, group chats and short-form platforms because they instantly signal embarrassment, immaturity and anti-climax. The extra-long delivery makes it stand out from a quick joke sound, so creators keep using it when they want a serious moment to collapse into nonsense. Its staying power comes from how universally recognizable the gag is across different video styles.
