I COMPLETELY disagree with the first definition, OK?
Firstly, to ridicule a town you don't even live in is just DISRESPECTFUL, IGNORANT, and to be honest a bit PATHETIC.
If you haven't noticed, There are teenagers drinking cheap cider in Wigan and Lowton too, so I don't think there's any need to single out Leigh.
And it's completely unfair to judge a town on the people who inhabit it.
The person who attempted to define Leigh before me HASN'T GOT A CLUE!
