A person who is habitually confused, scatterbrained, or foolish; a simpleton.
Compound of 'addle' (confused) + 'brain.' Formed in English as a colorful insult combining the concept of muddled thinking with the organ responsible for thought.
This is a delightful old insult that paints a picture—instead of just calling someone stupid, you're saying their actual brain is muddled and scrambled like an over-cooked egg.
