bat brain

a move personally made up from the batwing, a cruel joke, mostly done by other teenagers, where you take your scrotum, spread half of your sac out with your hand, and cup the other nut in your hand like a brain. takes a while to get right, but when accomplished, is better than the batwing

I flashed robert with the bat brain, and he threw up!

Adam scared a kid with the bat brain.

Silk Brain

The more wrinkles you have on your brain, the smarter you are. Having a silk brain is the lack of wrinkles on your brain, denoting extreme stupidity or inebriation.

"Nice move, silk brain."
"What a silk."
"Did you see Matt at the bar last night? He got silky as hell."

Brain Teaser

A story with a punchline. Used to tease the brain and produce laughter.

John: Bill looked in the mirror. He didn't see his own reflection but someone else's. He was not surprised or worried. What was going on?

John: Bill was looking at a photo!
Blake: Haha! That was a cool brain teaser!

brain fart

A sudden thought, seemingly out of nowhere, that has nothing to do with the topic you are discussing.

We were discussing the party when all of the sudden my husband had a brain fart and asked me to remind him to change the air filter on his car.
