But do people actually use such different language there? Are they mostly local older people or is it some modern fashion?
Our west coast has lot of people which are perfectly impossible to understand as they speak finnish and swedish mixed, young people use that too, but also there is one finnish dialect that is almost impossible to understand, that is dialect of Rauma this is quite fastly fading dialect as only elders speak it in original form, young ones don't use it because of nobody else would understand them but locals, so it would be bit of disadvantage in todays world.
Of course up north there is bit new words to learn and some meanings of words, I have learned that 'itikka' means mosquite, but up north it means a cow, so saying I squashed a 'itikka' would mean up north that I squashed a cow.
I don't know if it is any similar with east london slang, where they talk about boat race when they mean face, at least that is what this paper tells me about, but these local papers can be bit wrong, they claimed once that mobile phone sends GPS data to satellite
