666: WHAT IS IT?

So simple... when you hear it, you're going to be like of course it is, how did i miss that?  I'll tell you how you missed it, do a search for 666 and read the mumbo jumbo they've been filling our heads with.  Not a singe one of them tells you straight up what the deal is.  That's not exactly what "they" do... is it?  That's simply not prophet-able.
