Peter Griffin is the central character of Family Guy, the animated sitcom created by Seth MacFarlane that premiered in 1999, with MacFarlane also voicing Peter. His wheezing, repetitive laugh became one of the show's most quoted vocal quirks as episodes were clipped and shared online. As short form video and meme editing grew, the laugh was isolated into a standalone reaction clip that creators could drop into unrelated footage. It remains popular because the delivery is unmistakably Peter, so audiences understand the joke even without any episode context.
