Apologeez

A saying one can say when a sincere apology on your part is met with rebuttal / rejection. It can be used in scorn or sarcasm if the victim is in fact being annoyingly dramatic.

Bo: I'm sorry I jumped the shark. There was a trampoline and I was so pumped by my girlfriend and--
Jack: Yeah, you better be sorry, you ignorant prick! Thanks to you and your stupid waterskis, my Brucey-Wucey won't even be able to eat with planks in his mouth!
Bo: Apologeez… Forget I even tried.
