barking mad
Totally off kilter
Barking mad means completely crazy or insane.
The phrase is British slang, more colorful than simply "mad" and suggesting someone has lost all reason: He's gone barking mad if he thinks that'll work.
Sometimes shortened to just barking: You'd have to be barking to swim in that water.
