The black plague is a term used by people who cannot differentiate between the disease called the (bubonic/pneumonic) plague and the pandemic referred to as the black death (assumed to be caused by the 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.
Similar to the "Bieber Fever", the Black Plague is a very deadly disease, and highly contagious. Thanks to Rebecca Black, she has spread this new disease to million and possible billions of innocent people.
Logan: Ugh, Bro! I cant get that stupid Rebecca Black song "Friday" out of my head!!
Shane: Hmmm this sounds really similar to the "Bieber Fever".
Michael: No dude, its worse. I think Logan has caught..."THE BLACK PLAGUE!"
The Rebecca Black epidemic that has infected most of today's youth.
Black's new single, "Friday", went viral 5 days after being posted on a comedian's blog. The song itself is horribly written, composed and produced. Rebecca now has millions of views on youtube and has been twittered as much as Japan's crisis of 2011.
Wikipedia claims that her video is referred to as, "a youtube laughingstock" and there is not one critic that favors the song. Bottom line: she is famous for being shit at what she does.
Boy 1: Dude, did you hear about the song Friday?
Boy 2: What, that shit song where that girl can't choose what seat to take?
Boy 1: It's all over the internet, i want to burn my eyes out!
Boy 2: yeah man, it's the Black Plague.
