Barbarians are defined by actions, not sayings
Targ, suspecting a treasure in a room aflames, walks in.
DM: "You know the room's on fire, right?"
Me: "Yes."
Players: "Geez."
DM: "You rush into the room ... "
Me: "No, I stroll."
DM: "Ok, you stroll into a room aflames. Take 15 damage. Through the smoke you think you can make out a chest ablaze in the corner."
Me: "I open it."
DM: "But it's on fire."
Me: "I know. I open it."
DM: "You reach into the flames, taking another 23 damage. The smell of burned flesh fills your nose."
Me: "I pause and inhale deeply, remembering the smell of charred corpses piled upon each other after a successful raid."
Or upon finding an ogre's altar has a false bottom filled with decomposing bodies.
Me: "I jump in and start digging with my axe, ignoring any possibility of disease or infection."
DM: "The smell is just horrible ... awful ... you retch."
Me: "I vomit joyously, remembering the puking masses teeming from their huts after seeing their loved ones mowed down by my axe."
And it netted me 3000 platinum too. Nobody in the party complained once about the stench, which lasted a week.
