The real way to say innit.
Not 'init'

The incorrect way of spelling the london slang for "isn't it."
I mean, why not jst take it a step furthar, innnit perhaps? fools...

Contraction of isn't it.

Thought most famously used by -- so far as the writer understands -- "gangsta" English types, it's also used by Americans, though there is sometimes a tendency for it to sound more like "idnit", which might actually be worse because it's like...where'd the "d" come from?

aren't you

when you are in on a new trend.
Refer to british slang.

A word originally used in London post 90’s at least. Originally being used to mean ‘isn’t it’ in a shorter way. However it has spread to many parts over England and is now used as a patriotic word unthoughtful sassenachs throw all over the place, not making sense. Never used in any other part of Britain. Mainly used by teens without making sense. Although some adults can actually use it properly and respectfully.
