Nov 27 Word of the Day
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.

A girl (or guy) that looks really good from behind but when facing you turns out to have an ugly face or some other flaw that cancels out the nice legs and ass.
Man, that girl in the blue dress with the nice can was a total coin toss. Wish I'd called tails on that.
