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 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.

Brain Drain

when after jacking off for a long time or having sex for a long time and you finally cum and the load that you blow is so immense that you can feel your sack emptying out leaving the skin of it so tight that it constricts around your balls leaving your sack looking like a brain.

Dude i sobered up halfway through and saw how not hot she was and it ended up taking me so long to finish i definitely had some brain drain.
