wrong in the head—crazy; insane:
- When we read the first part of the saga, we naturally presumed Andy was somewhat wrong in the head.
wrong-headed—
1. persistent in erroneous opinion:
- To us, at that time, he was a wrong-headed young man who had thrown away a good career, and was vain enough to think he could be an author.
2. (of a belief, decision, etc.) wrong and irrational:
- The choice of Murphy was so wrong-headed that even some of the people who negotiated the deal were embarrassed by it.
