A British slang to call someone stupid

Actually originates from prison slang in the UK. A job often given to the lowest inmates was to put cardboard dividers into boxes. Someone given this job was a 'divider' or a 'div'. Now used as an insult to those who display stupidity.

A slang term for a stupid person

someone who lacks intelligence (an idiot)

a person that is stupid, or a insult

Div is a scouse word for idiot. It is short for divvy which in turn is a corruption of Deva. The Deva Hospital was a well known mental hospital (since renamed the West Cheshire Hospital) on the outskirts of Chester. Chester was founded by the Romans who named it Deva. Go on - you're impressed, aren't you!

Derived from "individual needs child", a cruel schoolyard insult. Not at all politically correct.

Someone who's "not quite normal", an idiot, spaz, etc.
