A Gregg is usually a kind and generous, but also a very complex person. Gregg is also a term used when describing anger or road rage. A Gregg is usually a prick to others for no reason at all.

The God in which Greggatologists worship. He is believed to have created the world, Wal-Mart, and Mexico. His son "Roy" is the messiah; he was hung by his testicles on a capital G. Roy now walks the earth as a pizza man, looking for righteous Greggatologists to give his Wal-Mart made pizza to.
You must accept Gregg into your bed if you want to go to Wal-Mart when you die; otherwise you'll go to Mexico.
