Peter Griffin is the bumbling patriarch of Family Guy, the long-running animated sitcom created by Seth MacFarlane, and his distinctive snicker has become one of the show's most recognisable vocal tics. Clips of the laugh circulated widely in Family Guy compilations on YouTube before being lifted for TikTok edits, reaction videos and meme soundboards, where its smug, knowing tone made it shorthand for mischief. It remains popular because it is instantly identifiable even without visuals, and it works as a quick audio punchline for almost any cheeky moment.
