Well, as you could probably guess it means that you are surprised. But it’
s surprised in BIG CAPITAL LETTERS with explosions, earthquakes and tidal waves followed by a total eclipse of the sun. It’s the sort of surprise that you would feel when as you were feeding your
cat she looked up at you and said “You’re fucking joking! I’m not eating that; it looks like puke and smells like shit! Get me some
chicken or a piece of oak smoked
ham, you arsehole.”
