Boink sounds belong to the long tradition of cartoon sound design, where a short spring or rubber effect was used to make a physical gag feel bigger than it looked on screen. Online, the same style of clip has been reused in short-form edits, meme compilations and slapstick videos because it is instantly recognisable even without any context. Its very short length makes it easy to drop into a single moment, which is why creators keep reaching for it for fails, bumps and exaggerated reactions.
