I don't get the "green day" thing, though he has a few other videos with that in the name... along with about 16,000 other videos.
This one was among the more frightening ones:

He writes it down. When he eventually dies, no doubt at the hands of his gangstalking persecutors, I hope his home/apartment/hovel is documented by someone for posterity.
'Green Day' is what he refers to any day where his confirmation bias suggests a greater number of gangstalkers wearing green and driving green vehicles. He also has days for every other colour of the rainbow.
Being a gangstalker sounds exhausting. I have to assume there are not gangstalkers dedicated only to specific people, right? They probably have a list with their assigned targets for the day and the color codes help them reduce redundant stalks.
For my part, I had no idea gangstalkers were so fashion conscious. Imagine trying to coordinate your outfit everyday to some random color scheme... Fashion forward, NWO shock troops!
It's easier than you think. As a gangstalker, your schedule is already meticulously micromanaged by our gangstalker overlords. When you happen to wear red, you will be scheduled to pass hundreds of targeted individuals on their Red Day, thus reducing overhead. Remember, as a gangstalker, you're always on duty!
Except during the third Friday of every month, that is casual day. Gangstalkers can dress in business casual defined as: No denim jeans, shorts, t-shirts, clothing with offensive language, halter tops, tube tops, worn-out or frayed clothing.
Just when you felt safe with the knowledge that you could recognize a gangstalker by a missing hubcap, broken headlight or the colour red, they go and pull this shit!
