Stretch marks on an ass. Ugly looking marks on an ass that resembles Freddy Crougar's face. Usually appearing during pregancy but men may have a dentass too. Men usually get them from steroids. There bodies stretch at a fast pace.

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.
