The boing has long been a staple of cartoon comedy, designed to imitate a stretched spring snapping back into shape. Animators paired it with bouncing characters, elastic falls and exaggerated physical gags, and audiences quickly learned to read it as a signal for silliness. As editing software made classic effects easy to reuse, the sound moved from television animation into online videos, memes and short-form comedy, where its instantly recognisable wobble still works because it needs no explanation.
