Nub soz is the biproduct of a nub and or nub cake and sometimes froobs. The word comes from sauce, this biproduct is usually embarasment or humiliation. The noob or nub can actually get good carma from this.
Like Runescape (I am not the owner Jagex made and owns Runescape) nubs and noobs some how get humiliated then an innicent person is booted or banned from the game.

Player1:Yur the worst player ever you fat froob nub licking durd!
