Peter Griffin is the central character of Family Guy, the long-running American animated sitcom, and his voice is instantly recognisable to fans of the show. This very short 'ni' clip circulates online as a standalone soundboard sound rather than as a famous line from a particular episode, which is part of why it works so flexibly. Shared in memes, edits and reaction videos, it is used as a tiny, absurd interruption that needs no context. Its brevity and familiarity keep it useful for creators who want a quick Family Guy reference without committing to a longer quote.
