Used in British English to refer to someone who is insane.

Also probably the most common mistake made by outsiders when trying to reproduce a British accent. For the record, it's either "he's a nutter" or "he's nuts". Saying "he's nutters" is a good way to make British people dislike you.
Good: "What are you, some kind of nutter?"
Bad: "Are you completely nutters?"
