I'm going to joke that a tv actor my fiancee likes is way out of her league.
Why do you want to tell her that?
Because she is out of my league, and I want to bring her down a peg.
It just seems really rude to insult your fiance like that. You should be supportive of them and want them to be happy.
I have the right to insult her and she's a bitch for impugning the honor of an innocent man.
You know there is no way they will ever even meet right? Saying harmful and insulting things to your fiancee is going to just get you both upset at each other.
