Does he have a Bragging Theme Tune? Because for some reason that post made me realise he should. Possibly with "Fistbeard Beardfist, of course." as the chorus.
When you're in trouble who do you call?
Who do you need when you're in a brawl?
Who is the drunkest dwarf of all?
Fistbeard Beardfist, of course!
Fists of iron! Abs of stone!
Balls of brass and beard of roan!
Fistbeard! Beardfist! Fistbeard Beardfist!
When orcs are invading who do you find?
When tentacled monsters attack your mind?
When elves are being snobby and unkind?
Fistbeard Beardfist, of course!
Knuckles like steel! Ale that's blessed!
Fist of beard and beard of fist!
Fistbeard! Beardfist! Fistbeard Beardfist!
