Peter Griffin is the main character of Family Guy, the long-running animated sitcom created by Seth MacFarlane that premiered on Fox in 1999. Because the Griffins are from Rhode Island, fans phonetically spell his name 'Petah' to mimic the New England accent, and the exaggerated introduction became a quotable meme format on TikTok and meme pages, in the same lane as character-intro clips like I'm Batman. Short uploads like this one circulate on soundboards as instant reaction audio, and the joke has stuck around because the mispronunciation is recognisable even to people who have never seen the show.
