The boing is one of the most recognisable sounds from classic cartoon sound design, where springy, elastic effects were used to exaggerate movement that could not happen in real life. As animation clips, memes and short-form video spread online, the sound moved from television cartoons into soundboards, reaction videos and edits, where a single bounce could carry a whole joke. Its popularity has lasted because the meaning is instant and universal: no explanation is needed to understand a spring, a stretch or a comic rebound.
