FIB

What people from Wisconsin call people from Illinois, can mean; Fuckin' Illinois Bastard, or a nicer version; Friendy Illinios Brethren.

I went to the Milwaukee Brewers game last night... The Cubs were in town, and Miller Park was full of damn FIB's

Fucking Illinois Bastards or Federal Investigation Bureau. Either a despective way of Winsconsin people to call Chicagoans or the FBI parody of GTA V.

I killed some FIB police officers yesterday on GTA Online!
I hate those FIBs!

Fucking Illinois Bastard

A lame excuse for an acronym orginated by Wisconsin residents in between daily inbreeding and masturbating to portraits of Vince Lombardi.

without these FIB's contributing so heavily to our economy we would all be poor and even more WORTHLESS.

Fuckin' Illinois Bastard

I have had a second home (cabin on a trout stream) in Central Wisconsin for over 30 years. Among my cheesehead friends in the local taverns, I am known as the King Fib. I don't regard it as perjorative; indeed, I am kind of proud.
