Per se
A word which is meant to mean “of itself” or “intrinsically” — it comes from the latin per se, which means “through himself” — but in ordinary parlance tends to mean “I am lying”, “I have no idea what I am talking about”, or “for your own sake, just ignore anything I have just said”.
Usage (real life example): “You see, I don’t see a bank deposit as a credit exposure, per se”.
