Comparative form of chaffy; more full of chaff, or more frivolous and less substantial.
From chaffy (full of chaff) plus the comparative suffix -er. Parallel to how 'grain' becomes 'grainy,' 'chaff' becomes 'chaffy,' then 'chaffier.'
Just like Shakespeare used 'the chaff must fall away'—the comparative 'chaffier' lets you describe ideas or talk that are getting progressively more wasteful and less valuable!
