Nai

Another way of saying 'isn't it' / 'isnt that right' or an alternative to the phrase 'innit'. Used more as a prompt to either recall someone's memory or to try and gain agreement.

Person 1: "I think I know that guy over there from somewhere"

Person 2: "Yeah, he looks like that Dylan guy we were in school with, nai"!?
