knock on the head
Hit the noggin
A knock on the head is a blow to someone's skull, whether accidental or deliberate: He got a nasty knock on the head when he fell.
Figuratively, to knock something on the head is British slang for putting an end to it decisively—killing an idea or plan: Let's knock this proposal on the head before it wastes more time.
