The act of jumping in motion, instead of running or sprinting. Mainly encountered in: every Xbox game. To do this press forward on the left joystick and rapidly press the (A) button. It is believed that this makes it harder for snipers and sprayers to hit said person doing the "Halo Jumping." This was first invented in Halo 2 in which multiplayer was first invented for Xbox. This is why it's called "halo jumping" for it originated in a Halo game.
Look at this gay little halo jumper, doesn't he know that "halo jumping" doesn't work in Call of Duty. *speaker then headshots the said halo jumper*
