loony
Off one's rocker
Loony means crazy or mentally unbalanced.
As a noun, it's a derogatory term for someone perceived as insane: The loonies have taken over the asylum.
As an adjective, it describes irrational behavior or ideas: That's a loony plan.
The word comes from lunatic, not from the bird—though loony as a loon plays on the similarity.
