To pull tightly on the skin around one testicle and squeeze that testicle up, isolating it. The resulting isolation of one testicle takes on the conspicuous form of a mushroom cloud after an atomic bomb explosion. Performing this trick with both testicles results in the popular "The Brain."

A stupid person; it refers to the lack of surface area on an individual's brain. The general thought is that the more surface area (wrinkles, creases, etc.) a brain has, the smarter the person is. Conversely, a person with a smooth brain (no wrinkles) has less surface area and would therefore be stupid.

That smooth brain is dumber than a pile of shit.
