Multi-place 

When people (usually Coloradoans or New Mexicans) insist or demand that another person be in one or more places simultaneously.
They seriously believe that people from other locations have this gift as they do, and will have a meltdown if you don't comply with this common demand (in their states.)
Not to be confused with multi tasking.
Multi-place means to have yourself in multiple places at once.

Your friend from New Mexico:
"Hey! Come over and have dinner with me."
You: "Sorry. I can't. I'm pulling a 14 hour workday with no breaks."
Your NM friend: "That's ok. Multi-place Come over right now and eat with me or I'm finished associating with you deadbeat from Iowa!"
You: " Please show me how to multi-place".
Or:
Boss one in Denver: "You're working 9-8 next Wednesday at my store, or you're fired!"
You: "I can't. I work 9-8 in Englewood next Wednesday at the other ____ store".
Boss one: "You'd better be at my store or else!"
Boss two: "You'll be working at my store that day and time, or else, New Yorker! Multi-place yourself like everyone else!"
You : (addressing both bosses from same company) "How can I be at your store while I'm at his store? How do I multi-place ? I don't know how to multi-place."
Both bosses : "Hahahaha that's for you to figure out, outsider! Hahahaha!"

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.

Bioshock 2's Multiplayer 

Developed by Digital Extremes and published by 2K games.

The vast majority of the High Ranking players pick the cheap Electrobolt/Elephant Gun loadout, which requires zero skill to use. Any loadouts that are effective against countering these players are considered "noob" and bawwww/ragequit about them only for them to use it themselves.

Instead of allowing the player to host a server on the PC version and pick whatever they want, the developers, much like most of the ones in the past 2 years (see Modern Warfare 2), got dropped on the head and decided to use a match maker, which typically puts the player in matches that are almost over or with scores such as 490-10 and placing the player on the losing team or in matches with the host lagging and disconnecting everyone.

A Map Pack the Rapture Metro was released in May 11 2010 for Multiplayer. In it contains 6 new maps for user's enjoyment. Unlike the Tester Pack or the Character Map Pack, which were already included in the original game files (you still had to pay money just to use them), not everyone has the DLC. As a result they never show up on the match maker. 2K officials have promised a future patch giving a DLC map loadout but no patch was ever developed. In addition, the last DLC "Minerva's Den" was not released on the PC.

The overall lack of polish in Bioshock 2's multiplayer mode may have contributed to an annoucement that Bioshock Infinite may not have multiplayer shipped with it upon it's release.

Player 1: "Well Bioshock 2's Multiplayer was one of the biggest disappointments of my life. I spent $10 on the DLC map pack and I learned I can't even play it 99% of the time."

Player 2: "Stfu go play it on a private match"
