What's a bogan?

I'm in slightly sketchy territory here, as despite having been told, I don't have a precise handle on what this is myself. I know it's not exactly a compliment, but I have a feeling I'm never going to know more than what I do now so I'm going to try to explain.

My dictionary of Aussie slang defines a bogan as a "young lout." It's a person without, shall we say, the most refined of manners? I hadn't sensed that a bogan had to be "young," and I think I felt a few more connotations of socio-economic challenges, perhaps with touch of the coarse? And maybe there were particular geographic areas bogans were more likely to come from?
Australians, am I close? Can you help me improve this?
