Gamer Rage 

You don't wanna come across a Gamer with a burning rage, this is the most dangerous apex predator you could ever meet. This happens when a Gamer is interrupted, dies a lot, or is mocked in game leading them to exceed the limits of human emotion. In this state no one within a 500 mile radius is safe, one wrong move and you could be incinerated by the touch of these entities. They have the power to rip anything to shreds, usually the very device that gave them the rage. May lord have mercy on those who come in contact with such a force of nature.

It looks like Daniel has gamer rage, please don't approach him as he can and will end your life.

Gamergate 

A word used to describe the events following on from an otherwise minor scandal, where rumors that a games journalist had a relationship with a developer that he hadn't disclosed during his coverage were met with a series of articles from across the specialized gaming press, in an apparent attempt to demonize their own readership, coordinated behind the scenes on a secret mailing list.

Gamergate represented a massive failure of journalistic ethics and was responsible for a number of people losing trust in games related media and even the wider news industry.

Gamerfag 

A gamer with no other life, doesn't know anything about realism, thinks old games are the best, buys a new computer often and does not know how to manage a computer properly.
Most gamerfags are cod players on Xbox between 12 and 30 years of age, some play wii games, some buy the BEST or most expensive gaming equipment and claim to be hardcore or pro-gamers.

I am sick of these Gamerfags ruining my online community.
Stop being a Gamerfag... move on from your Quake 3, CS 1.6 and CoD4.

Gamertag 

A gamertag is a person's online persona over xbox live.

You need to pick it wisely as Microsoft will try to get as much money from you as possible because it costs 10 dollars to change it.

Also there are unwritten rules when it comes to creating your gamertag.
Rule #1: It may contain at least 1 marijuana reference.
Rule #2: It may or may not (your choice) reference alcohol or boobs.
Rule #3: It must have 3 x's somewhere in the gamertag (perferably at the beginning and the end)
Rule #4: If you are 12 years old and are planning on playing halo 3 all day after school until your bedtime you must put MLG in the beginning of your gamertag.
Rule #5: You must, MUST make it look you're so retarded that you spent your whole time as a baby in a washing machine.

Here are some examples of gamertag you might want to use.
