What's the last thing you roared about?

Last night I came back from the gym. I was really tired and smelled pretty bad, but I was feeling really strong so when I got to the top of my stairs I stopped at my door and just roared. I don’t really know why, but that’s what I did.

Do you see this as an acceptable thing? What are some things you’ve roared for? Am I just crazy? What does a roar mean to you?
