Commonly used Canadian phase, born out of the excessive usage of "sorry", this statement allows the user to conform with the sintax of apology, but indicate that he is, in fact, not sorry.
Often used in situations where an undue amount of judgement or prejudice is being applied. A simple, direct way to tell the person their feelings/thoughts/opinions aren't changing your mind and you will not apologize.
Sally: "is that wine? Are you drinking while pregnant!?!"
Jane: "it is wine and it is my choice, Sorry I'm Not Sorry."
Your NOT actually doing anything other than impersonating me out of spite because Jordan Peterson doesn't like the fact that I applied his metric to that retard. You don't actually care as long as you get to play supreme moral debate arbiter which is why Jordan Peterson probably likes you so much. You both want to be the golden prophet but you're not actually capable of being that without being INSTALLED (deliberately) by other people who want to shut ME down. You're an ancillary (or even tertiary) villain I the story of the greatest mind who has ever lived (Creator of A.I.)
