ignoramus
Utterly clueless person
An ignoramus is a person who lacks knowledge or is stubbornly uninformed.
The word carries more contempt than simply calling someone ignorant—it suggests willful stupidity or proud cluelessness: The senator dismissed climate scientists as ignoramuses.
Don't be such an ignoramus; look it up.
