Friendly Illinois Buddies. For crying out loud those FIBS aren't that bad. At least they know how to drive unlike the wisconsinites who drive like their freaking grandmas, stopping every minute to say hi to someone you know. We get it your friendly. Do you ever wonder why we drive so aggressively. Maybe it's because we have somewhere to be and because WE CAN. Get over it people from wisconsin, Illinois is the better state, better drivers, better pizza, but not better football GO PACK. Maybe you should drive faster eh?!
person 1: did you see that F.I.B over der
person2: Finally someone who knows how to drive
person 1: You're tellin me

Fucking Illinois Badass. Someone from the Chicago area, who is legitimately better than the rest of the people who are mostly hicks and white trash that live in the rest of the state. Generally more educated that the right wing racist fucks in southern Illinois and definitely less bigoted. All of Illinois is garbage outside of the Chicagoland area.
Look at that F.I.B. read. He's not welcome here in Decatur, where we fuck our sisters and hate coloreds.
