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 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.
