one shot

Term, often used in Halo, to identify an opponant in which one shot to the head with most weapons (Battle Rifle, Magnum, Carbine) will kill said opponant. In other words, the player has no shield. Commonly used in serious MLG games, this term is often combined with the location of the player. The purpose of using this term is to request assistance from a nearby teammate in killing the opponant, because in most cases the player identifying said opponant would be unable to do so. It is important to remember when using this term in-game that it is only effective when paired with a specific location of the player.
