I always laugh when I hear someone say:
"I don't mean/want to complain, but"
I want to say to them, "then don't".......Obviously you want to complain, so why preface it with that? The same can be said "I'm sorry if I shouldn't say/do this" and then they say it or do it anyway.

One that truly annoys me is "conversate". "You and I are gonna have to conversate." I had someone say that to me, and I replied with...
"No, we can either converse about something, or we can have a conversation, but we can't "conversate."
