A S. is overlooked by many, overheard by everyone. They once were normal people. Their fault-finding, wisecracking, know-it-alling turned them into monsters went to their heads, which consequently exploded and left... a throat. They concentrate on finding the fault in anything and derail any discussion to pointless little flaws. They're common everywhere, where there is an "opposition".
How to fight it
Arguing is pointless, even if you have a more up-to-date Dictionary. I find it entertaining to set up a meeting between a S. and a [Hool]. The S. are physically dreadfully inferior but would never admit it and talk the Hool into a frenzy.gab
