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.

*The codename for the atomic bomb that was dropped on Hiroshima on August 6th, 1945.

*The man of a character in MGS2; he's basically a fat-ass albino in a thick, highly-advanced EOD (Explosive Ordnance Disposal) BDU (Battle Dress Uniform), and is armed with an infinite quantity of C4's and a Glock 18. He looks and sounds like he could be a mafioso criminal or something......given his weight, he'd be more like a crimelord.
