Just for the expression used on Blizzard's Game "World of Warcraft", meaning that a group of players that are below the recommend number to clear an instance (dungeon) have the skill and cunning to do so. Usually dungeon groups are made up to 5 players, which one has a specific role like healing, damage or tanking. But once on a while you can see groups of 3 or 2 players that can handle an entire instance, using the expression as "personal pronoun" + "number of players" + Manning. This can be done using characters who can heal or uses pets to taunt or provoque enemies or abilities like fear or other controlling attack.
