Meat-Brain

A person of generally limited imagination, who originates and passionately carries out hair-brain schemes, or idiotic shenanigans. While religiously insisting on being completely deck out in commando gear or home-made ninja customs.

Two Meat-Brain (s), Robles and Raftery, stalking a larger, out of touch and some what paranoid kid, Palmieri; in a cemetery, while dressed in bdu’s and pretending to be ghost.

hanging brains

When a dude pulls his hairy balls out of his zipper and attempts to walk around the bar and pick up unsuspecting chicks. The irony is that he is actually using the only brains that he has!

Brandon Abby was hanging brains at the bar last night.

brain egg

Similar to a "lightbulb moment", a brain egg is when you have an insight--preferably if you aren't trying for insight.

Jimmy Jim Jon: Dude!
Bocefus: What dude, what is it?
Jimmy Jim Jon: I just had a brain egg dude, we don't need explosives we'll just use.....
