The line comes from Chris Traeger, played by Rob Lowe, in the American sitcom Parks and Recreation, where Traeger's relentlessly positive personality became one of the show's most quoted traits. Fans clipped his emphatic delivery of literally and shared it as a standalone reaction sound, especially in edits and memes that needed instant, over-the-top agreement. Its brevity helped it travel across short-form video and soundboards, where a single familiar word can carry a joke on its own. It remains popular because Traeger's voice is instantly recognisable to fans of the series.
