Animaniacs premiered in 1993 as a Warner Bros. animated variety show starring Yakko, Wakko and Dot, known for fast slapstick and exaggerated cartoon physics. Boing sounds were a staple of that style, borrowed from classic animation where springs and Jew's harps voiced impossible bounces. Clips like this boingy effect later spread on soundboards and in meme edits because the tone is instantly readable even without the picture. It remains popular for parodies, kids content and reaction videos that need an old school cartoon feel in under three seconds.
