Extremely stupid or silly; showing a lack of intelligence or common sense.
From 'moron,' a term created in 1910 by psychologist Henry Goddard from Greek 'moros' (dull, stupid). Originally used scientifically for people with mild intellectual disabilities, it became a general insult.
This word was once a medical diagnosis, but it's become so common as an insult that it's now considered offensive—it's a reminder of how language around intelligence can become weaponized against people.
