Stfunoob 

The greatest empire our world has ever seen. It stands undefeated in battle thanks to superior training in their troops and sage-like wisdom from their leaders, such as Roflmaool. Also, it stands for "Shut The F*** Up Noob." (Noob obviously a derivitive of the word n00b, which comes from "newbie.")

Oh no! Our nation is being attacked by Stfunoob! We are now destined to perish!
