In MMO games, players typically fight against creatures in the game, to be rewarded with currency or items from the defeated creature. A player is said to pull the creature when they begin attacking. They are in essence "pulling" the creature to them, to attack the creature at a closer distance. Pulling is done so creatures focus their attacks on one player, often a tank, who can take damage. Healers in the group can then focus their healing without getting attacked while everyone else in the group assists in killing the pulled creatures.
