This is a combination of 3 seperate words. "Bitch" "Nigger" and "fantastic" it is used mostly on Xbox Live by trashtalkers who are amazed by the opposing team's final victory kill cam on Call of Duty 4 Modern Warfare.

The statement expresses amazement while at the same time distain for the opposing time.
