wind in the head—
1. vain imagination or conceit:
- He has probably got wind in the head through living in that gorgeous Gothic pagoda.
2. unpredictability or flippancy in behavior:
- “Wind in the head,” the servants called it. But it was but the natural consequence of the state of mental and bodily idleness in which she was placed.
Note: The expression does not correlate in meaning with the compound airhead—(U.S. sl.) smb. who isn’t very smart; a stupid person:
- “Spell check” can’t save the truly illiterate ones. How can such airheads ever manage to graduate?
windmills in the head—foolish projects or notions:
- These windmills in the head are what apparently drive state policies about “national security.”
