This is a baseball pitch that gets the kind of spin similar to a spiral thrown by a quarterback in American football.
There is much debate as to whether the pitch actually exists, but Japanese pitcher Daisuke Matsuzaka allegedly throws such a pitch, similar to the slurve(cut fastball/slider) but he is usually extremely vague, saying that he has only seen the gyroball-- in japanese comic books.

This is NOT my website, but there are a number of sketchy videos on the internet such as this where it is unclear what kind of spin is on the ball. If and when Daisuke Matsuzaka signs with a major league baseball team(as of october, 2006 he has only pitched in japan), people will surely be talking about the gyroball.
The gyroball is a mythical pitch in baseball that like bigfoot, may or may not exist.

A popular drinking game, originating in Arlington, VA and gaining national acclaim in the summer of 2007.

It is played with three tables. One long table in the middle of 2 smaller square tables (note: the 2 square tables should be waist heigth and the long table should be appx. a foot shorter) and a ping pong ball.

The object of the game is to bounce the ball on the long table and get it to bounce as many times as possible on the opposing team's smaller square table.

Each bounce counts for 1 point. The first team to 11 points wins (note: the teams always get the same number of shots, so if the team that shoots first gets to 11 first, then the team that shoots second will have a shot to tie them).

In the event of a tie, the 2 teams will enter into an overtime round. The overtime round has the same rules as the regulation round, but the teams play to 3 points instead of 11.

If a player gets the ball to bounce 11 times on the opposing teams table it is called a "Gyro Ball". If the ball bounces 11+ times and comes to rest on the opponents table it is termed a "Perfect Gyro Ball" (Note: Only 2 Perfect Gyro Balls have ever been recorded and only 1 of those was during competition).
Let's play an exciting drinking game like Gyro Ball.

Gyro Ball is much better then Beer Pong.
