The boing became a staple of classic American animation in the mid twentieth century, when cartoon sound libraries used elastic spring and jaw harp effects to exaggerate every bounce, stretch and recoil. As those cartoons were repeated on television and later clipped online, the sound became shorthand for slapstick in edits and memes. It now sits alongside other goofy ahh sounds in meme soundboards, where creators drop it over gaming clips, TikTok fails and reaction videos whenever movement looks unrealistically springy or a joke needs a light, physical punchline.
