The boing is a classic cartoon sound effect rather than a line from one film or game, and its exact original recording is not documented in the facts for this clip. Springy effects like this became a shorthand for bouncing, stretching and comic surprise in animation, and later spread through games, memes and short-form videos. Creators now reuse the short clip alongside other quick cartoon noises, including a pop sound effect, because it is instantly understood without explanation. Its brevity keeps it useful for fast edits, reaction videos and playful soundboards.
