Etymology

Cuckoo (informal) is often used to mean 'a fool', and a helpful way to remember this is to think of the bird's odd habit and its simple repeating call 'cuckoo'. Because the bird does strange things like leaving its eggs in other nests, people began using its name for someone acting silly or strange.
