When a man ejaculates into his own hand and then proceeds to throw it onto someone else.

"Dude, did you hear about Bobby? He gave this one chick a Norwegian Fastball at the party last night!"

Avacado Fastball

When you are equipped with a micro penis and can't perform so you choke your scrotum until it turns green and beat her ass with it.

Joe, you see how Marge is walking? That's cause I beat her ass with my avacado fastball last night.

Shake off a fastball

It means going number 2 in the bathroom. In baseball, when a pitcher wants to throw a fastball, the catcher puts one finger down. If he wants to throw a curveball, he shakes his head to the fastball and the catcher puts 2 fingers down for a curveball. Also known as "calling for a curveball".

I need to go to the restroom and shake off a fastball

High Fastball

Another expression for taking the dirt road or taking the brown eye from Atlanta to Boston.

Last night I switched it up and gave her the high fastball. Your mom always hits the high fastball.

underhanded fastball

Jerking off in a public restroom stall while doing a handstand. The ejaculation must take place in less than 15 seconds after the jerking commences, and to truly perform this dead the load must be caught in the mouth of the one jerking off.

Dude I passed this girl walking through the mall yesterday. I got so hard I had to go into sprint to the restroom and pull an underhanded fastball.

stinkfinger fastball

When a baseball pitcher uses a substance on his finger when he grabs the ball, and when it crosses the plate, it smells so bad the batter backs off the box for a called strike.

He threw that stinkfinger fastball by him, made him look like a fool, boy.
