The gay ass way that people wear their hats nowadays. They even leave on the gay ass round shiny stickers that tell you how small the casing for your brain is. You used to shape your bill into a curved thing that would fit snugly on your head...back when it was cool to wear a hat.
"Damn foo, look at all those wannabee gangsta's flatbillin it!"
"I can't believe you're using a flat bill...you used to be cool!"

Get the flat billmug. The most retarded looking thing a human can wear on their head. Usually worn by teenage or mid-20something males to look "cool."
"Look at that tool over there, with the Flat Bill Hat"
"Check out my hat!" "Sorry bro, you look like a retard."
