The boing has been a staple of cartoon sound design for decades, created originally with spring and string instruments to mimic elastic movement in animation. As classic cartoons moved online and into meme edits, the effect became shorthand for anything bouncy, clumsy or unreal. Creators now use it alongside other jump cues like Mario Jump in gaming videos, and on its own in TikTok and YouTube Shorts to signal a joke landing without needing any dialogue or explanation at all.
