Without meaning to sound too cheesy on the subject, I was trying to come up with a workable definition of "horror". 
I mean some people think that any thing with gore equals horror.  But to me, that's just shock value not really horror.
Is horror anything that deliberately scares you?  If that's the case, then John Boehner is the king of horror!  (Sorry, I will try to keep politics out of this.) Let me know what you think...
