Not to be confused with the Bieber Fever, having the Black Plague is one's way of supporting the teen-singer Rebecca Black, and her viral hit single "Friday."
Despite the song's negative reviews, supporters with the Black Plague still exist to this very minute.

The sickness provoked by a startling, unprepared for viral attack by the name of "Rebecca Black." Symptoms include beign followed by 30-year old black men while sitting in your school bus and having to make the unorthodox decision of trying to decide which seat to sit in.
Aw, man. I was only trying to youtube Charlie Sheen and i accidently stumbled upon the black plague!

Possibly the best horror game on the planet working in five hours (unfortunately) of intelligent gameplay and brilliant story accompanied by a feeling of vulnerability as the only thing you can use is the ability to run from the skeletal monsters that _can and will kill you_. Lacking in some texture detail but excelling in every other aspect including but not limited to atmosphere, brilliant soundtrack, admirable voice acting, compelling story, very interactive physics, psychological destruction, and challenging puzzles, this game is simply amazing.
Penumbra Black Plague is the shit man.

Used to describe a person who is fascinated by Rebecca Black or addicted to her viral hit-song "Friday". The phrase is like how "Bieber Fever" is to Justin Bieber.
Jake blasted the song "Friday" from his phone in front of the whole class, infecting the students with the Rebecca Black Plague.

A buying event larger than Black Friday,

This marks the day after a President of a Country shuts traveling borders to Europe sparking of a prepper buying frenzies.

First things to go are:

* Hand Sanitizers
* Toilet Paper
* Face Masks
* Canned goods
Did you see the line at the grocery store this morning? It was a new kind of Black-Friday, "Black Plague Friday".
