I am looking for suggestions for role-playing an evil, half-orc barbarian. He has an Intelligence of 7 and a Wisdom of 12. He is savage (raised by orcs in the underdark) but not outright vicious or diabolical. Frequently I'll speak in orc or undercommon (which no one in the party understands orcs and only one other person speaks undercommon) instead of common even when others speak to me in common. Needless to say, I say "Oops" a lot and then repeat myself in broken common. Generally I won't do outright silly things like try to pick up crabs and have them attach to my fingers with their claws (I do have above average Wisdom) but I will kick fragile things around not thinking about how easy it is for me to break the object (Strength is 20). Any additional ideas such as what my character could say or actions he could do would be appreciated.
