out to lunch

Not paying attention

Out to lunch literally means away from one's workplace for the midday meal: She's out to lunch until one.

Figuratively, it describes someone who seems mentally absent, confused, or out of touch with reality: If he thinks that plan will work, he's totally out to lunch.

The slang sense suggests a failure to grasp what's obvious to others.
