At first, I didn't know what "innit" meant but I've come to think it's really "ain't it?" As in "isn't it?", just said and written differently.
Is that wrong too?
It does mean “isn’t it”, but it is used when “isn’t it” would be grammatically incorrect.
“I went to the shop yesterday innit?”
“I’ll do that later innit”
“My arm’s been hurting all week innit”
Or as general agreement:
A: “She’s a total bitch”
B: “innit”
I don’t know exactly where it came from, became very popular in the late 90s.
I wonder if it was originally a British Asian thing? I have heard extremely posh older Indian doctors say things like “we should start a betablocker first, isn’t it”, so I wonder if “innit” is just what their kids say.
