Black Snow 

Black snow is the unofficial term for the soot that inevitable falls after a nuclear strike. Because a nuclear strike vaporises everything in a short radius it is burned to ash and sent into the sky with the force of the blast. Due to most of the mater in the ash being completely destroyed it has a very low density and is carried by any wind for a decent range of a few dozen kilometers/miles. The ash then falls to the ground like a light snow(except black/dark gray). Because of the radioactivity of the bomb the black snow is highly radioactive and lethal, if you see it run to your nearest fallout shelter or basement.

Jim: Hey look snow!
Bob: Black snow.
Jim: What does that mean?
Bob: Well that means someone nearby just got nuked.
Jim: Want to build a snow man?
Bob: No, I'm going to hide in the basement.

Blacknowledgement 

This is the process by which a Black person acknowledges another black person's presence in a social environment where black people are scarce or otherwise absent. These environments include places and events like: lacrosse parties, ice hockey games, early morning classes, Russia and The Ku Klux Clan Annual General Meeting.

Blacknowledgement is a show of solidarity and support indicating to another black person that you understand their social anxiety and feel their inner torment.

A blacknowledgement can be executed using anything from a simple nod to a well executed six part, click and snap, integrated handshake. In less friendly situations, a blacknowledgement may be used as a territorial gesture. It can be used to signal to another black person that you are the resident black person in that environment and that they should cower off and find non-black friends of their own.

When one consumes so much alcohol that they have lost their mind and become blackout they tend to partake in activities that they wouldn't otherwise do. Usually causing them to become a shitshow therefore the combination of blackout and shitshow is blackshow.

Suzie was so blackshow last night that she puked in the rice maker and then proceeded to steal a puppy from a child.
