loose screw
Not quite right
A loose screw is an informal way of describing mental instability or eccentricity.
Someone who has a loose screw or has a screw loose isn't thinking quite right—their mental machinery isn't properly fastened.
The expression is usually mild and humorous rather than clinical: There's a loose screw somewhere in that guy's head.
