Peter Griffin is the central character of Family Guy, the animated sitcom created by Seth MacFarlane that premiered in 1999, with MacFarlane voicing Peter himself. Clips of his distinctive voice have circulated on soundboards and meme pages for years, often shared under misspelled titles like Move Petey Grifith. That mangled spelling became part of how fans find and repost the clip. It remains popular because a single bossy shout from Peter instantly signals cartoon impatience without needing any setup or context from the episode.
