brain erection

When you have a large problem, and you're stuck because you cannot figure out the answer. In which case the only thing to do is think about or preoccupy yourself with something else, and let your brain erection go limp so that you can go back to the problem in a fresh state of mind.

You: I've been working for hours and can't figure out this homework! It's too difficult, why would they give us something that's impossible to learn?

Friend: Dude chill out you just have a massive brain erection. It needs to go limp, just go play with your pet squirrel for a bit.

(Later)

You: Hey this homework makes sense now!

crystal brain

noun

1. a keen mind, formidable intellect

2. that which an intelligent person uses to predict future events instead of a "crystal ball"

This term was coined by comedian Adam Carolla on his morning radio show to combat a harpy lawyer who was insisting that she couldn't possibly predict what an obvious outcome would be because she didn't have a crystal ball.

Reasonable Person: That new Sandler movie is gonna blow ass.

Douchebag: You don't know that. You don't have a crystal ball.

Reasonable Person: I don't need a crystal ball; I have a crystal brain.
