Green Shivers 

The cold rush you get after smoking a joint of weed. Usually makes you shake quite abruptly which lasts for a short period.

Person 1: Hey man, try some of this weed, it's good stuff!

Person 2: Nah dude, I've had enough, I'm so cold, I've got the green shivers.

"Hey, let's get off the slopes and find a green room."

Green Knight 

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?
