I started a barbarian and I would love to hear some stories of barbarians who are more than get angry and hit things.

I'm still fleshing out my guy, but he is an older orc who travels around as hired security/promotion. He doesn't want to always jump to violence but he knows his build and race makes intimidating people easier, so he kind of feel into the bouncer roll and has gotten good at being frightening enough to deter most minor thugs and problems. He does have a nasty temper that he works to control. He is a giant instinct barbarian, so I'm trying to figure out a good reason why he uses such a large weapon and eventually can grow larger.
