Flat earther

A person who believes that the state of being level conforms to a plane and rejects all evidence that a level surface can actually be curved.

Bev is the most annoying type of flat earther, because he rejects the term saying that mountains and valleys and hills mean that it’s not flat.

Flat is justice

It's true though. Flat IS justice, anyone who says otherwise clearly doesn't get the appeal. It's elegant, it's understated, what else can I say? No, I'm not trolling. I frankly don't care if not a single man in the world shares my preferences, flat is justice and that's a fact!

Imagine liking bouncy, buxom, full-figured breasts, like ew. Flat ass and tits are MUCH more elegant looking (not too flat though). Flat is justice.
