I think you're a no-nonsense kind of guy; you get angry with reasonable things and when you are angry, you are angry. I wouldn't call you a hot head, nor a temperamental person, you just have low tolerance for sh!t.
I agree with everyone above, given the little amount of time I've interacted with you, haha. If you truly consider your anger a problem, remember to take deep breaths and attempt to empty your mind of that which weighs you down.
I don't find you to be an angry person. Just because you get mad, it doesn't mean that that defines you. Like what everyone said above me, we all get annoyed sometimes, that's all.
