Jewish antics. Derived from our jew cocksucker Gary, Jantics is a term used to describe the worthless shit that spills from his mouth on a daily basis. Ant type of antics that comes across as self centered and completly irrational.
Say you give this "gary" a five dollar bill to pick you up an item at the store that will only cost two dollars. When he arrives with your item, there will be NO change. Attack of the jantics.
