The line comes from the world of SML, the long running YouTube puppet comedy series created by Logan Thirtyacre that began with Mario plush videos and later moved to original puppets.

This one spread as a standalone soundboard clip rather than a full scene, passed around in meme edits and chats where a short, sure answer works better than a long explanation.
