NAG 

NAG was an incredible group of badasses who ruined everyone's day in EverQuest. Activities included training Dragon raids, causing mass NPC fights in Shadow Haven, and generally just being totally rad. NAG was lead by Nytro, who was much like Hitler, except for the genocide.

You're as cool as NAG!

Nag 

Commonly heard in smoke filled gambling holes in reference to a horse who has performed in a sub par manner and has usually cost a bearded old coot his fortnightly welfare cheque.
Often implies the animal in question may be only a short trip away from the glue factory.

NAG 

"Naval Academy Girlfriend" - the term affectionately bestowed upon the girlfriends of the United States Naval Academy (a prison-like college where Midshipmen (students) are put through many trials and tribulations which ultimately affect the life of their NAG). These women band together and have formed a sisterhood to support each other and their boyfriend/fiance.

Midshipmen A: Did you hear they changed the weekend policy?

Midshipmen B: Yeah, my NAG told me that a week ago. They find out everything before we do... it's scary.

Midshipman A: *sigh* I wish I had a NAG...

Nag 

A word invented by chauvinistic men to insult and belittle women who have to ask them to perform a small task multiple times before they actually decide to do it. Used primarily by lazy people to justify the fact that they show no inclination to do anything productive whatsoever.

Gary: My sister Chloe is such a nag. How dare she suggest politely that I peel my fat ass from this couch and clean up the mess I made in the kitchen!
