When something is so disgusting that you gain sick pleasure from it or get turned on because it's just so gross.
Like when the perky cheerleader in the horror film gets her head chopped in half and blood and gore squirts everywhere, and you feel that rush-type-thing as you scream. Or when you're reading a really terrifying story and you're like squirming around in anticipation of what happens next and all giddy and scared.
Basically getting excited by something creepy.

-Have you seen Madden 2006 for the Xbox 360? The graphics are gonna be awesome!
-Dude, the Madden 2006 images they showed at E3 were bullshots. It doesn't look nearly as good as they said.
