A Greg in the wild will often drink in excess and then lose all sense of self. Others around him are often left red faced and ashamed that they have taken a Greg under their wing. Don't let a Greg fool you, they will go by another name to cover up their true identity. Watch out for these predictable creatures, approach with caution!

That guy is such a Greg..
Don't start Gregging out on me now.
