Flat

Very drunk, but in a lethargic sense. The term refers to the vertical position of one laying down or passing out on account of heavy drinking.

"Man, I wish I hadn't drank all that gin before the party. I was completely flat the entire time we were there."

Flat Brimmed Energy Drinker

Somewhere between a skittle thug and what you would find under flat brim. But most applicable when applied to downhill mountain bikers. They have an affinity for chilling at the trailhead bumping gansta rap and puffin' tuff and are physically incapable of getting their $5,000 bicycle up the hill so must coordinate with a cohort to shuttle themselves up and down the mountain with their two $30,000 pick up trucks. As you can see, this becomes a financially burdensome endeavor, especially when you take into account the 5 Monsters they consume per day.

You flat brimmed energy drinkers are douchebags!
