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.

1. Quite literally, to fuck in the skull. This usually means inserting one's penis into any orifice in the head (excluding the mouth), such as the nostrils, ears or a hole bashed into the back of the head with a pair of pliers. As this is not only rather painful but quite impossible in most cases, skullfucking is not a common practice in real life (unless you're talking about necrophiliacs that is). It is, however, tolerably prevalent in the world of hentai art, resulting in pictures that are more horrific than sexually arousing. My advice: don't seek out any of these pictures unless you have an uncontrollable urge to lose your lunch all over the keyboard. See also skullfuck.
2. See mindfuck.
3. Can also be used as a kind of insult.
1. I love skullfucking ^_^
2. Damn, watching Memento will give you a bloody good skullfucking.
3. Skullfucker!
