Mainly used by people in Halo 2.
OMG this guy is a sword whore.
Is a descendant of "Pistol Whore." While the ancestor arose from Halo: Combat Evolved's multiplayer, "Sword Whore" has arisen from Halo 2's multiplayer. Essentially, a sword whore is a player who, in the eyes of his opponents, uses the energy sword far too much. It's ease of use, sheer killing power, and the fact that in virtually all gametypes only one player in the game will have it, make the sword a particularly envied weapon. It gives the wielder a devestating advantage in mid to close range combat, as it has a fairly long "lock-on" distance. That is, if your enemy is close enough to you to do damage with the SMG (the usual default starting weapon), he is close enough to you for the sword to "lock on" to him. Pull the trigger, and you lunge forward, closing the gap almost instantaneously, and scoring a one-hit kill.
Since only one player in the game has the sword, and it takes nearly perfect timing to dodge a sword lunge, the wielder is virtually invulnerable--provided he is not a complete idiot, and pays no attention to where his enemies are/might be.
Any gamer, and even a casual observer, would make the obvious conclusion that the sword is a dominant weapon, and anyone choosing NOT to pick it up is somehow cognizantly flawed. However, many, many players will, upon being killed by a sword-wielder, scream out the the swordsman has no skill, shouldn't be playing halo, and is a n00b
A person in halo 2 who has the sword for most of a online game.
Dude noob234 is such a SWORD WHORE.
