Fart Brain

1. Someone who's head is devoid of nominative brain tissue. Similar to the more common air head the cranium of the subject contains nothing but gas. However in this instance, the gas inside the cranium consists mainly of stinky gut methane.

2. Someone who consistently brain farts.

"I admit that I slept with your best friend, honey but honestly, it didn't mean anything."

"Why don't you just fart off, fart brain?!"

hungry brain

An act, usually public, in which a man hangs his scrotum out of the fly of his pants, pulls the skin tight around one testicle with his hand, and squeezes rhythmically, resulting in a veiny, throbbing effect reminiscent of a 1950s science-fiction monster.

Usually considered vulgar.

They're still talking about the time he walked into Denny's and flashed the hungry brain.

Baby's Brains

A man's scrotum.

The balls, particularly when it's chilly and they're tucked up tight against the body. The foldy skin looks like the brains of a tiny baby.

"Ugh, I just caught a glimpse of your baby's brains...put those things away!"

Brain Bang

Brain Bang is used to describe how you feel after witnessing something mind blowing or seeing something amazing and out of this world. It can also be used to describe how you feel after realizing something crazy, like an epiphany on steroids.

Josh was brain banged when he realized that there was an arrow in the Fed Ex Logo and that OK is a stick figure side ways.

How did he pull that bunny out of that hat!? Man, what a Brain Bang.

Whoa! Inception gave me a crazy brain bang the whole time I was watching.

Cubone is a baby Kangaskhan!? BRAIN BANG.
