Gamerchat 

A condition in which a person makes frequent typographical errors while gaming, for the most part disregarding grammatical errors that would otherwise take up valuable time to correct. This is typical when a player needs to focus mainly on the game and much less on their typing.

(In-game chat):

Player 1: Thisa gauyh as ilke 500 seigteanks in eed halpe@!

Player 2: Wtf dude, I could barely understand you...

Player 3: Gamerchat much?

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.
