Peter Griffin is the main character of the animated TV series Family Guy, created by Seth MacFarlane. Short clips of his laugh have circulated for years in soundboards, meme compilations and reaction edits because the voice is instantly recognizable and exaggerated. Online, people use it as a quick audio punchline for jokes that feel childish, chaotic or shameless. Its staying power comes from how little setup it needs: even a one-second clip clearly signals the character and the tone.
