a pool (pocket billiards) term. The foul committed when the cue ball is struck twice. Specifically when that first little touch is followed by a reflexive jab at the cue ball. This is a portmanteau word--that is, a word carrying two meanings. The stroke is a jabitzer; the cueist is also a jabitzer. This invented word won a $25 prize for best new word of the week--partly because its creator wrote I think it`s a transitive verb. Didn`t look like a verb to me.
