Holmgang was formalized viking dueling. Got beef? Let’s holmgang! But hold up a sec tough guy, we’re not a bunch of wild men! There’s rules God dammit! Before each duel, and since it was a incredibly honor bound society, the combatants would lay out the rules. “What weapons are we using? Will you bury me with my weapons? What do I get if I win?” Essentially, ritualistic smack talk before the fight.
Loosely translated Holmgang means, a walk on a small island, and on a small island is where the duel were traditionally contested, “Hey! You’re a jerk! Let’s go over to that small island and bash each others’ brains out.” - Some pissed Norwegian guy.
