A dice-rolling cheat who never loses. They roll so good, they might as well have a magic dice that only rolls sixes.

My brother rolled a 20 on his first try. He’s definitely Galactus.

My friend cheated so hard in D&D, the DM called him Galactus.

I rolled a 10, and my friend rolled a 20. I asked him if he was Galactus.
