For those of you who don't spend your spare time hanging out with geeks and trolls on the Internet -- let me explain GamerGate. Usually, "___gate" refers to a scandal, but in this case, it refers to a gigantic online mob that thinks there's been a scandal when there hasn't.
The whole thing began when some guy named Eron Gjoni posted a big rant about his girlfriend lying and cheating on him. You can read it if you want to verify that people in their early 20s really still are as immature as when you were in your early 20s. Gjoni comes off as a caricature of the self-absorbed, whiny millennial guy, while his girlfriend, Zoe Quinn, sounds like the kind of woman that one should learn to avoid very early in one's romantic life.
