This nickname was actually formed in the southwest, actual place is unclear, kinda sounded like grandma was refering to Miss/Tenn/Ark area, when I talked with grandparents, they explained to me that it was a term used when 2 people married who was related but was so far removed that their only relationship was by geneology.
And yes Elvis made a song about it, kinda funny that he made that song and he is from the same area in which the saying supposedly came from.
