The 'muffin button' line comes from Team Four Star's Dragon Ball Z Abridged, the long-running YouTube parody where Goku is written as cheerfully clueless. Fans clipped his silliest one-liners and shared them on soundboards, Discord servers and meme edits, where this one stood out because it has no context to explain. It survives as a pure non-sequitur button, useful whenever a creator needs an instant burst of TFS-style absurdity without quoting a full scene.
