burns flat

A dry, windy, dusty as fuck, air-force abandoned little town in western Oklahoma populated by impoverished, gun-toting, bible-thumping, ignorant, trump-loving redneck hicks that wouldn't know a good law if it jumped up and slapped them right smack in the damn face. Truly the arm-pit of America. If you spend anytime there, your IQ will plummet 50 points.

Dropout 1: "I feel dumber."
Dropout 2: "Why?"
Dropout 1: "I drove out to Burns Flat."

Flat

Commonly used to describe a girl with the tits of a 10 year old annorexic male. Can be referenced to as an acronym, meaning "Forever Lacking Any Titties".

Person 1: I gotta say, Emma's pretty hot, I think I'll go for it
Person 2: Are you joking?? She's as flat as the Great Plains!

Alternatively, with the acronym in place...

Person 1: I gotta say, Emma's pretty hot, I think I'll go for it
Person 2: Are you kidding me? She is, and will forever, be F.L.A.T

(The first instance is much more commonly used)
