look up any word, like swag:
 
1.
A person who overuses the Battlerifle, usually used in Halo 2. Since the auto update's modification to the BR (battlerifle), it has been way to powerful and led to this term. The word 'whore' can actually be put after any weapon, escpecially rockets or sword.
"w00t. These guys suc...ugh...that Battlerifle whore shot me."

-Why did you betray him.
-He was a BR whore.
-Ohh. Okay.
