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.
