Smooth 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 fucking smooth brain put his shirt on backwards again...

That smooth brain is dumber than a pile of shit.

hard-on

Man's most magnificently majestic manifestation of masculinity, and the one potentially most exciting to a woman. It looks like a rocket ready to be launched, and has the same turbulent thrusting force and energy.
It signals to a woman that a guy is ready and able to have sex with her and eager to do so, which, if she finds him attractive, tends to kindle her interest. For that reason, it is a serious though common mistake for a guy to be embarrassed or self-conscious when he has an erection.

Freshman year, after pulling an all-nighter, I stripped and got in bed, only to wake a half hour later with an urgent need to piss. I got up without waking enough to know I was naked, much less that I had wood, and walked down the hall to the bathroom. Only as I walked past the open door of another room down the hall and saw a woman grad student staring at me with wide eyes did I look down and see I was sporting the most giant hard-on I'd ever seen in my life. Afterwards, she kidded a male grad student we were both friends with that I had a better body than he did. He replied, "You've seen more of it than I have."
