"Bring a Friend" - MMORPG slang for the habit of some mobs (enemies) of drawing aggro (attack behaviour) from one or more additional nearby enemies to the character when pulled (attacked by the player). An enemy which exhibits the behaviour of drawing more than one enemy to the player when pulled individually is a BAF mob.
