One who drunkenly panics and starts freaking out over mundane events. The act of freaking out may or may not include drunkenly shouting, crying, and generally being a jerk to everyone in an exaggerated emotional woe-is-me way.
Dude, everything was fine and then he totally Gregged out out of nowhere.

That guy is such a Greg..

Don't start Gregging out on me now.
