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.
