The Kool-Aid Man began as the cheerful mascot of the Kool-Aid drink, famous in television adverts for smashing through walls with his catchphrase. Family Guy later turned that image into a joke, staging a courtroom moment where a chorus of oh no gives way to his sudden entrance and triumphant oh yeah. Clips of that reversal spread online as a short meme sound, shared for entrances, reveals and unexpected wins. It endures because the reference is instantly recognisable even to viewers who have never seen the full episode.
