bubbleheaded
Lacking serious thought
Bubbleheaded means foolish, empty-headed, or frivolous—as if the head contained nothing but air.
The term often carries sexist overtones when applied to women, evoking the stereotype of an attractive but vacuous person: a bubbleheaded blonde, some bubbleheaded celebrity.
It suggests someone more concerned with superficial matters than serious thought.
