What does when someone say you are mean means?

I have no clue really , but if somebody called me ghetto.Well, ghetto means that there is a street house that can't be fixed.That means whoever they are saying is ghetto is too awesome to be fixed.That's what I think ghetto means.I get called ghetto alot and that's what I think it means.It also means a slum.That means whoever is calling what is a slum.That's how it goes.If you were Break Dancing and your to awesome to be fixed.Old stuff that's what that means , but I don't know what it means if somebody calls somebody else ghetto.Somebody help me out what does ghetto mean I'm trying to explain what ghetto means.Or they could be calling you christian.Which I like the slum idea.
