The north and south nod is a condescending nonverbal expression of disdain

While I agree it is disdainful, TEd Rem, I'm not sure anyone would want to be disdainful to a General. So at some levels it is merely dismissive.

re: "Play Chinese Squabble at www.chinesesquabble.com": Shouldn't people have to pay rent for repeated billboard exposure like that?

It's not that I have anything against "Chinese Squabble", whatever that is, but how do you refuse someone promoting "Ukraine Ucher"? Or Chinese Qumquat?

In fact, I have a slogan of my own I would love to promote.
