Jafaikan is the language of British people who talk in a fake jamaican accent and use words like 'bizzle' 'blad''shizzle' 'innit' etc etc etc
They arent always white either, theres a lot of asian and black Jafaikan speakers out there.
"chill out blad, look at them beanies cutchin over there innit tho"
"You what mate? oh right youre a fuckin Jafaikan yeah"?
