Didn't his kindergarten teacher ever tell him to use his inside voice and play nice? Was he raised under a rock by a heavy metal singer? Why not simply start a conversation by yelling and swearing at this person and when they ask you why you are yelling and swearing at them, ask them if they like it. When they say "no", tell them that this is the reason why yelling and arguing is bad. It gets you no where but in a vicious cycle of heated bickering and high blood pressure. So unless this person wants to have an aneurysm and die, I'd suggest not yelling, arguing, screaming, bantering and whatnot.
