I heard this term on TV from the lips of one of the lawyers who argued the Heller Case before the US Supreme Court.
The gentleman was talking about the nebulous term "Assault Rifle." Actually an assault rifle is fairly well described in military terms, but when the term is used by politicians or even some police it becomes something more amorphous.
The speaker suggested we use the term EBR—or Evil Black Rifle to describe this thing that is (a) a rifle and (b) scary.

PS: I decided to add a new category, SCOTUS, for Supreme Court of the United States, to better label this blog post.
