Stewie Griffin is the scheming infant from Family Guy, the long-running animated sitcom created by Seth MacFarlane, and his voice is a staple of meme culture. This particular clip circulates mainly on Portuguese-language soundboards, where 'fralda' means diaper, and it gets shared alongside other baby meme clips for quick comedy edits. Like many short cartoon voice bites, it spread through reaction videos and meme compilations, and it endures because Stewie's voice is instantly recognizable.
