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.'

Flat Earther

A low IQ science denying idiot (most of which are also whackjob conspiracy theorists and antivaxxers) who believes the Earth is flat but could never come up with any intelligent arguments to prove his or her point. These people are far too stupid to even qualify to ride a short bus, probably from banging their head against the roof of said bus far too many times as a child.

Buzz: Have you saw that documentary I sent you earlier on flat earth theory?
Max: Yeah, it was complete bunk.
Buzz: How so?
Max: No actual science to back it up for one thing, just a bunch of anecdotal crap from a group of low IQ simps
Bruce: Science is overrated and is a crock
Max: OK, glad to see that you lack any degree of common sense and intelligence. Can't wait until you become a victim of natural selection. If you take a group of 5 or 6 of you flat earther types, you MIGHT finally reach a combined IQ of 30...if you're lucky.
