He's a southern woofter. You can tell because he punctuates every sentence with "innit". This contraction of 'isn't it' which itself is a contraction of 'is it not?' Is designed to assert a statement as a rhetorical question where the rhetoric is not clear, placing the onus on the recipient to confirm or reply and turning isolation postulates into conversations. There is zero historical literature which presents this as a formality. Not all English men approve of this lexicon.
