Flat as a plank

When you pretty much don't have boobs.

flat mouths

Cheap sneakers possibly bought at K-Mart or Kash-n-Karry. The have flat soles, no cushion, and make a slapping sound when you run.

Look at kingfresh wearing his flat mouths! What an anathema!

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!"

Flat Earther

The very very very derogatory term for "braindead".

Did you know that the natural habitats of a "Flat Earther" are the YouTube comment sections of Flat Earth videos?

flat food

Flat food is any food item that comes out of a vending machine and can be slid under a door. Flat food is often used by management to subsist software developers slaving long hours to meet a deadline (death march).

I just fed Bob some flat food so that should keep him coding at least another four hours.

flat ass

Blunt honesty, absolute truth bare of cushioning social niceties

Derives from the impossibility of reassuring a person with insufficiently pleasing buttocks

Q: Do these jeans make my butt look big?
A: Girl, no jeans in the WORLD gonna help THAT flat ass!
