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.

Post intercourse, the man ejaculates into his hand, then winds up the Suicidal Semen Fastball firing it at his partner as fast and hard as he can, flinging the semen all across his partner's body.
" My boyfriend launched his Suicidal Semen Fastball at me, plastering semen all across my face. There were no survivors."

A baseball pitch that looks like a typical fastball to you, then mindfucks you by dropping out of the strike zone as you swing, utterly humiliating you and making you look like a third-rate bushleaguer. Swinging at this pitch and missing is like getting hit in the face by a freight train--you should have seen it coming, but it's just too damn good for you.
You need an example for this? Seriously? Fine. That thar guy on the mound sure throws a mean SPLIT-FINGERED FASTBALL. Are you happy now!?
