out to lunch


Not in touch with the real world, crazy; also, inattentive. For example, If he believes that story, he's really out to lunch, or Anne hasn't heard a word you said—she's out to lunch. This expression transfers a temporary physical absence for the purpose of eating to a temporary or permanent mental absence. [Slang; mid-1900s]
