The term Lunchbox referring to an absent minded individual or “Freudian slip” may have evolved from the phrase “Out to Lunch” or “mentally checked out” for the moment. Later, the term Lunchin was added to refer to an action, event, thing, and person (basically a noun). A Lunchbox is a person which makes you want to Facepalm!
