bxr 

A halo term in which you press "B, X, R" on the controller. By pressing "b" (or whatever you have melee set to), it'll melee and by pressing "x", it cancels out your melee, and by pressing "r", it'll shoot. By doing this in one smooth motion and accurately, you'll pull off an insta-kill.

BXR 

A series of buttons to press in the Xbox game Halo 2, used somewhat frequently in Xbox Live matches and LAN Tournaments. By pressing B(Melee), X(Cancels Melee animation)and R (Shoot) In succession, when you near an enemy, you will successfully take down his shield, and kill him with the three shots from a Battle Rifle (This is the only weapon for a true BXR to be used successfully.) BXR can save you from close firefights as you can kill an enemy almost instantly, regardless of your health and shield bar.

A halo 2 combination.

Also: a small but weirdly chubby and nice-to-fondle breed of piglet which walks on its hind legs, plays games all day and makes a peculiar noise when you prod it. Also happens to be the only type of piglet that can swim.

BxR 

A BxR is a button succession in Halo 2, in which you can use any human weapon and select covenant weapons to instantly kill an opponent. With default controls, you press the melee button, "B" by default, to beat-down, and as soon as your attack meets its target, hit X and R as fast as you can keeping your target reticule on their face. This will drop their shield, and kill them if done correctly. As said before, this can be done with a pistol, a sniper rifle, a battle rifle, and carbine.
