Ready and excited is a generic hype phrase rather than a quote tied to one known show, game or creator, which is part of why it travels so well online. Short reaction clips like this are shared on soundboards and in short-form videos because they can be dropped into almost any upbeat moment without needing context. Creators use it to signal enthusiasm at the start of a video, a game session or a collaboration, and its brief length makes it easy to reuse across edits, streams and memes where a burst of energy is all that is needed.
