Fucking Illinois Bastards or occasionally, Fucking Illinois Bitches. Shortened to the acronym "FIB."
It is an unkind term used by Wisconsinites to refer to the residents of Illinois. Common times to use this are:
1. In reference to how Illinoians Drive - very fast and offensive.
2. Their vacationing choices - Wisconsin Dells and Lake Geneva.
3. Bears Fans
1. That FIB fucking cut me off on 894!
2. FIBs are taking over the whole state in the summer!
3. When was the last time those FIBS won, 1985?
