spit ball is a   Noun

Definition:

[1] A pitched ball in throwing which the pitcher grips the ball between two, or three, fingers on one side (which is made slippery, as by saliva) and the thumb on the other side, and delivers it so that it slips off the fingers with the least possible friction. When pitched directly overhand a spit ball darts downward, when pitched with the arm extended sidewise it darts down and out. [Cant] -- Spit baller.
