Saw something in Shadowrun that made me think of a trait for Pathfinder
Warriors Honor-Trait-Whenever you encounter another warrior in peace time, you want to challenge them to a nonlethal duel. The nature of the dual is a fight to first blood using nonlethal blows. If you Win the duel, you gain a +2 bonus to social checks with this character as you have proven yourself superior to them. If you fail, you gain a -2 penalty to social checks due to your overawe of the character. If the character will not duel you, you consider the person below you, which grants a +1 bonus in intimidate checks and a -1 penalty to diplomacy checks.
