When you see someone heating something in a microwave at work, home or the gas station you cup your hand around your butthole and fart. With the fart trapped in your hand you open the microwave and drop your fart. Some variations have the fartballer screaming FARTBALL at the fartballed. Others live with the quiet satisfaction that only an anonymous fartball can provide.
"I used to hate my boss. Then I started fartballing his afternoon coffee and I feel better."

The Four Seam Fastball 

The act of using four of one's fingers to administer a handjob. The hand is not in the normal jacking off position, but rather the giver of the handjob comes from above and wraps all four fingers around the penis of the recipient. The position and movement of the fingers looks somewhat simliar to the movement of a jellyfish's tentacles, a lobster's claws, or how you would hold a baseball when pitching a four seam fastball. Invented by Elise, made popular by Muffin and Wills.
Elise gave Jack the four seam fastball, and Jack had to correct and show her the real way to do it.

Jellyfish Fastball 

This move is done after engaging in doggystyle secks. The man ejaculates into the woman's vagina. He then holds his hand like a cup underneath the semen (Jellyfish) filled vagina. With his other hand he grabs the woman's side and begins to tickle her. If done correctly it will cause a muscle contraction that forces the semen from the vagina into the cupped hand. When the woman turns to look back to see what is going on, that is when the male siezes the opportunity and hits her right in between the eyes with a Jellyfish Fastball.
That bitch was so pissed when I hit her with a sidearm Jellyfish Fastball!

Reagan Era Fastball 

A fastball in the mid-80s.

In reference to Ronald Reagan's presidential term from 1981 - 1989.
A Reagan era fastball for strike two. That's mid-eighties.
A sport played in the USA. One of the few existing sports where obesity is required to play. Primarily played by fat men. The object of the game is to get in as many sex positions as you can with your fellow male opponent within 11 minutes, and give Budweiser an excuse to show beer ads for an hour, while fooling viewers into thinking the real objective is to touch the ball down in a designated area of the field in 60 minutes. So boring and gay it cannot be played outside the USA, because people of other nationalities do not have the required qualities, i.e. short attention spans, weak bladders and outright homosexuality, to watch two seconds of it without puking and running out of their houses with wet towels on their heads, shouting,"That's(expletive) gay!"
52% of fatball viewers prefer watching Budweiser ads than the sport itself. gayball queerball fagball

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
