empty-headed
Lacking any intelligence
Empty-headed means lacking intelligence or serious thought—someone whose head seems to contain nothing of substance.
The term often carries dismissive or contemptuous overtones: an empty-headed socialite, Don't be so empty-headed.
It suggests frivolity or vapidity rather than mere ignorance.
