Looking at the shady 10 sec video that only shows a link and a user commented "fuck you" I'm guessing its a virus or some type of browser hijack script.
it links to the same vid. put the link in one of those url shortener decoders like on brizzly. it clearly shows the link to that video LOLJK IT WAS A VIRUS AND I INFECTED 1K+ PEOPLES COMPUTERS
Meh, it's not that bad at all. Don't worry about it. Warning: Spoilers inside! OH, THE HUMANITY, DON'T CLICK THE LINK
