Brain Bean 

Adderall acquired from someone with ADD taken in order to perform better in an academic setting.

Usually I sleep through math class but since I popped that brain bean I'm excited to learn. I even know how to solve problems using formulas I don't remember learning.

brain-box

This refers to a person's head, usually in a crude or uncomplimentary way. A berk's noggin or (rarely) a desktop computer's tower.

"Go soak your brain-box" is a suggestion to go drown yourself in a bucket. "He banged his brain-box on it" means a berk finally figured something obvious out.
