2.
This is a term in which its origin came from the midwest region, mainly ohio. There was a family with multiple generations of Doctors and heavily educated individuals. In the mid 80 that family gave birth to its last boy. He ended up having no college education and got married to a woman who was heavily educated and so was here family. What Leebird stands for is being the underachiever of the family.
