Group slut fic. Refers to a type of erotic fanfiction in which any and all members of a particular (usually all male) ensemble cast have crazy sex with each other. Probably originated in popslash fandom.

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.
