TBF, I think it gives an accurate representation of people born out of Newcastle but pretend to be Geordies. Middlesbrough, Easington etc. Not actually fully-fledged Geordies, but crave the attention that Geordies have (sort of like Mackems really)

I actually think that Greg seems normal. He seems like the misfit in a bunch of ****ing goons. That Charlotte (the Smoggie) is a ****ing disgrace to the NE though
I'm pretty sure there's only one that is actually from Newcastle like... as to which one that is I have no idea.
