Peter Griffin is the central character of Family Guy, the animated sitcom created by Seth MacFarlane that premiered in 1999. His laugh became a standalone meme clip as short Family Guy excerpts spread on YouTube, Vine, and later TikTok and soundboards. Editors isolated the cackle because it works without context and signals instant amusement. Like the baby laughing meme, it survives as a quick audio shorthand for finding something ridiculous, and it remains popular in compilations, edits, and reaction posts.
