The cartoon boing is a stock-style comedy sound that became widely recognizable through animated slapstick and gag-heavy editing across TV, games and online videos. Rather than pointing to one single famous source, people usually know it as a generic spring boing used to exaggerate bounce, recoil and rubbery movement. It remains popular because the sound instantly signals cartoon physics in under two seconds. In meme edits, it often fills a similar role to the Vine boom sound, but with a lighter and sillier tone.
