Smi: You go clubbing?
Townie: Yeah innit
Rabson: You're only 12!
Townie: Yeah innit don't ya mate?
Townie: Oh ma God-a like! I can't believe ya don't go clubbin' innit!
only for the reason that they're to lazy to say
I mean why would you want to spend the time it would of taken to say that extra 'it' when you could be robbing some old ladies purse, huh?

2. An irritating and totally meaningless word that uneducated youths or asians add to the end of a sentence, implying that the few words they have managed to string together is actually meant as a question, regardless of whether it is or not.

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?
"Dude, that is kinda bad, innit/idnit?"
Innit can be used anywhere in a sentence and can be used sarcastically, complementingly or just innit.
'What you looking at innit!'
