A contraction of sorts, combining two words: fucking and ignorant. A simpler and more direct way of describing a persons mental density, especially when there are small ears about that maybe shouldnt hear certain swear words. Usually reserved for those who excel at being ignorant, especially used on the road behind someone who doesnt know a turn signal from a canuter valve, much less common courtesy and basic traffic rules. Can be used in other venues and situations where a person displays stupendous amounts of ignorance far beyond that of mere morons.
A snooty person who is stuck up and looks down at others not of the same ilk. A friend and I made reservations to eat in a high end restaurant when we walked an older coupled looked at us and apparently didn't think we belonged. The woman made a face crunched up her nose and made an audible hmmph sound. My friend said "What is she doing trying to blow a fig out of her nose"? This also was quite audible. The woman then said "That's disgusting" to which I replied "You're the fignostral"
