Try watching the film Sweet Sixteen, it is set in Glasgow and I had to put subtitles on just to understand what they were saying.
This is common in Essex "I'll shank you bled! Brap Brap"
I don't even know what Brap even means.
I don't understand Glaswegians, infact they are insulted for their accents in Falkirk and Edinburgh. The above sentence I said in Scottish meant "Hey, you're on benefits" as it is quite common usage in Central Scotland (Most people here have shitty Council Houses, yet these people are richer than those in regular housing that those regular people have to pay for.) I don't live on benefits so I guess that's great.

If it want some East Anglian words, watch Hot Fuzz not only is it a great film but it has characters mainly from Norfolk and Suffolk but it is set in Gloustershire. It has to be one the best films I have ever seen.
