By KAC

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?"

A mentally unwell person. One who is crazy/pyschotic. It's a brain condition which is inherited and makes one act in irrational and insane ways.

People think im a nutter. I must take after my father.

An absolute loose cunt who does the sickest and funniest shit and is always good to have around for a laugh. Everything a Nutter does is shaded with a tinge of crazy. Lacks awareness and is a lunatic, doesn't have it all quite there upstairs, but will act like a muppet, show off and be the nuttiest nutter.

Sammy: Did you see my Dragon Knight last night? Absolute nutter, mate. Sschliiiiike! Farmsy: I don't talk to account buyers. *Sammy is kicked from server*
