Flat Brained

Flat Brained (Flatius Branium) is a common condition where the victim goes into a nearly catatonic state and shows no signs of brain activity, unable to achieve basic cognitive thought and anything above basic involuntary muscle work. Victims tend to constantly say and do utter nonsense and continue to do such until their vital organs eventually shut down.

Someone take the sandpaper away from Johnny, he's going to go flat brained again.

Flat Brainer

AKA Flat Earther, they belong to the Flat Brain Society. They think the Earth is flat and that some evil dudes made it a globe. You cannot argue with them, they have bogus logic and get very angry when you prove they are wrong.

I was banned from a flat brainer discord after proving their argument wrong! lmfao
It went like this:
Him: "That lens represents atmospheric refraction"
Me: "Actually, the atmopshere acts more like a wedge lens, not a fresnel lens"

(I don't actually know the correct lens, I was just setting up a trap.)
Him: "How can you prove that it acts as a wedge lens?"
Me: "How can you prove that it acts as a fresnel lens?"
Him: "You are just doing hand-wave dismissals, you are yet to answer my question!"
Me: "Are you kidding me?"
*gets banned*

That guy is a flat brainer, he thinks the earth is flat. No power in this world can make him think otherwise.
