It's one character's answer to the question "You have impressive control over your anger, how do you do it?" and it makes no sense. But because the question and the answer were an hour apart, everyone was fine with it, I guess. I only saw Iron Man(s) before Avengers, but that line was when I was sure every other Marvel film was going to be Content, not movies.
I have one, from Avengers: "I'm always angry."
