imbecilic
Lacking basic sense
Imbecilic describes behavior or ideas that are utterly stupid or foolish.
The word derives from imbecile, which was once a clinical term for intellectual disability but now functions primarily as an insult.
Imbecilic carries strong contempt: The board's imbecilic decision cost the company millions.
It suggests not just poor judgment but a fundamental lack of sense that the speaker finds exasperating or infuriating.
