d6'er
A d6'er is someone who thinks a d6 is the best weapon in D&D, even though it’s barely better than a rock.
My d6'er brother tried to fight a troll with a sword and a d6. It didn’t work.
My d6'er friend used a d6 to roll for everything, even when he had a d20. It was sad.
My d6'er neighbor said his d6 was magical. It wasn’t. It was just broken.
