Multiplayerfag 

In gaming, someone who buys and plays video games purely for the multiplayer. They can be found mostly on Call of Duty games as well as Halo games.
They are the type of people who want multiplayer in all games.

One example would be the upcoming Dead Rising 2, in which multiplayer was added thanks to the increase of multiplayerfags.

If it weren't for multiplayerfags, many game series such as Halo, Gears of War, and COD games wouldn't have so many sequels.

Bob went to buy a quality game, he bought Dead Rising and enjoyed it very much.
Fred(Multiplayerfag) went to buy a multiplayer game, he bought the newest generic halo sequel.
