Flat Earther

An utter moron who thinks that the Earth is flat. It is often difficult to sway them into thinking that the Earth is actually round. They often make YouTube videos about their 'proof' that the Earth is flat, which is often debunked by people that know Science.

NOTE: Despite what facts you state, they will refuse to believe you and say 'You've been converted.' or 'NASA is lying to you.'

Person 1: "Hey, look at that guy, he's a flat earther!"
Person 2: "Yeah, what a bafoon."
