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 pitch which is doctored by the pitcher to make it have a bending motion as it comes to the plate.The pitch is thrown with a different grip than the fastball in that a pitcher wedges the ball in between his fingers and delivers the pitch as if he were slamming his fist down on a table. This creates topspin on the ball which makes air moving around it curve to the axis rotation of the pitch.

A flash game online that is essentially an updated, 3D version of the classic 'Pong'. Many claim to reach high levels like 12 or 20, but they are lies, as the source code reveals the highest level as 10. Based on online research, I am the only one who has ever reached level 10. But I have only done so once, and it is impossible indeed.
1. I am the best Curveball player in the world! I got to Level 10!
2. Dude, I was playing Curveball the other day and level 9 was bringin' the heat tenfold!
