Stands for "National Guard." Usually applies to individuals who are, in fact, weekend warriors, but think that they are the most badass "Army" guy out there.

They talk about basic training constantly, and always take pictures of themselves in their gently used uniforms.

A typical nasty girl facebook post: "Random Drill Sergeant quote... HOOAH!!!!!"
That nasty girl always has to tell everybody about anything he does Army related.

They named themselves the nasty girls becasue they are nasty, gross, slutty, ugly, fat, and rude. No one likes you, you are failures at life. Stop trying to be sweet, and your name? Lets brag about how gross we are
Fuck the example they can suck it
