2. A gay, bisexual, or trans-attracted white male.

That guy Tyler is logged into 8chan 23 hours a day. He's an undercover Greek knight for sure.

Exactly like white knighting(defending something with blind loyalty at every opportunity, regardless of any legitimate complaints from anyone else) but specific to Razer gaming products, even in threads where Razer wasn't mentioned at all.

Robert(totally not Krakoff) read a tweet about a new keyboard release from some other company and started to green knight in the thread, bragging about how it doesn't even have macro keys or stupid marketing gimmicks. Bro, do you even hype? Can that keyboard even connect to the lights in your car and animate the dashboard with awesome effects?

A Green Knight is an overzealous and obsessed fan of said product(s). Green knighting is defending a company's product(s) with blind loyalty at every opportunity, regardless of any legitimate complaints said company receives from anyone else about their product(s).

Reading through the tweets, there are still Green Knights who will defend this bad game.
