It is a condition where you turn 5' 7" 210lbs and have a somewhat southern accent in the north. You will either drive a beat up primer gray chevy truck, a souped up cavalier, or a firebird. You smoke like a chimney and chew like there's no tomorrow. You will have a high pitched somewhat annoying voice and very short hair.
If you're named Andy in Tunkhannock, then you suffer from Andyism.
