A chud is a name coined by Zil to describe a mutant freak who, in Zil's view, has done something extremely morally wrong. This was used after moof was dismissed.
It was first used when Zil used it to describe Hunter.
Zil coined the phrase when calling Hunter a "murdering chud" after Hunter accidentally killed Harry. The word was used when Zil tried to convince the crowd to hang Hunter during the events of Hunger.
