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!
You must be a right div to
waste yer time writing out definitions that nobody gives a
toss about.
