My, my, them Aussies! We Yanks would NEVER, EVER put a curse on our President. Everyone here praises him and heaps blessing upon him. At least, I've heard a lot of invoking the Deity and the President at the same time even though I couldn't quite catch the rest of the words. 8-)

"Shame on you!" is or can be a curse too.

According to Powers, a "widow's curse" was exceptionally potent because it was given by someone who had little else left to her.
