Flat Earthers

People who put years of research and hardwork into waste by considering the Earth to be flat. These people are probably retards from birth.

I'm phobic towards flat earthers.

Flat food

Flat food are waffles and pancakes or something that's from a vending machine if you do business duty.

If you watch the Mr. Men Show on Cartoon Network, Boomerang or YouTube, you'll notice something about Miss Whoops' problem with eating pancakes.

The only food that does not count are: pizza, sandwiches and cookies

Miss Whoops: "Pancakes?? I really don't like flat food!"
