in‧nit /ˈɪnɪt/ British English informal
[Date: 1800-1900; Origin: isn't it]

1. used as a way of saying 'isn't it':
It's cold, innit?

2. used after a statement for emphasis, instead of any question tag. This use is very non-standard and is grammatically incorrect, but has become common in spoken English among some young people:
He's a bad man, innit (=used instead of 'isn't he'.)
