brain bomb

An instance where, no matter what you say afterwards, saying (absolutely) anything in defense of yourself will just make the situation much, much worse. If a brain bomb occurs, it is best to shu your trap and either

a: take the aftermath as a man, or
b: get the hell outta dodge.

Most commonly, this is done by a man to his wife, or by a man in general.
Instructor: ...What could possibly have driven this female to do such a thing?

Male student: Must have been that time of the month.

All female students in the room: *Gasp*

Male student: Damnit, brain bomb.

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.

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.
