Continuity mistake: At the end of the movie Gabe and Roy are sitting in the bleachers and Roy is wiping his forehead with a towel as Gabe starts talking to him. The camera zooms in and Roy now has his arms folded on top of the towel with his legs crossed.
Factual error: When Fitz and the Diggstown boys are playing 5 card stud poker, the cards are supposed to remain on the table. However, Corny has his cards in his hands, like they're playing 5 card draw poker.
Answer: Maybe it's just a local reference known only to the local residents of Diggstown. Then again, I can't find any info on the town of Diggstown either.
Diggstown, GA is a fictional town.
