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.

An alien looking mofo who has an extremely small penis and has a hobby of inserting large sharp objects into the anal cavity. Typically a Gregg can be found in slums of most neighborhoods offering blowjobs to minors for a jolly rancher. If you see a Gregg, report them to the closest police department immediatly.
