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.

Flat Earth

The most retarded theorist group to ever exist, becoming a Flat Earther poses a high risk to your IQ, and has a possible side effect of giving you Cardiac Arrest, And/Or Removing your brain entirely.
some flat earthers belive in an ice wall (Antarctica ) surrounding the earth, with outside lands that the rest of the world is hiding.

Flat Earthers have two siapses in their brain and nothing more

Flatbill

A retarded kind of hat worn by greasy highschoolers who wanna act like they're from the hood and adult degenerates who refused to grow up . If you want to look extra insufferable combine it with a neck tattoo.

That guy in the flatbill is unsurprisingly a degenerate
