The spring boing is a long-running cartoon-style sound effect rather than a quote tied to one famous character. Variations of this wobbling spring twang have been used for decades in comedy editing, animation, games, and meme videos to sell bounce, recoil, and slapstick timing. Online, it remains popular because viewers instantly understand the joke: something stretched, snapped back, or moved in an exaggerated way. It often appears in the same kind of punchy meme edits as vine boom sound or SpongeBob Fail.
