the word means - winnings or victories but acctualy-
this is the true explanation.....
eyal barkan used to raise his hands just at the 'aliya' - the breaking of the track at the peak -when the beat gets under and the melody prepares for the peak and then it comes back strong full power...
so he was, at parties, like a conductor on the crowd to dance (conductor in hebrew- same root as nitzhonot)...
and that's the true story
