Let's see if I can think up a few:

Finished with your Christmas shopping? People say it so much it's like "How are you?" when you know no one really wants to know how you are. And what if I hadn't? What kind of sadistic bastard takes pleasure from people floundering at the last minute?

Saying "literally" when you don't mean "literally". I'm sure we all know it. No need to put an example here.

What are you doing to my vagina? I'm so sick of my wife saying that.
