At the time of this writing, Kappa Kappa Kappa is not a
Greek-Letter Organization, and I sincerely doubt that anyone will ever charter such an organization. (Well, at least not until they run out of the other 13823 permutations of 3 Greek letters and decided that 2 and 4 are right out.)
For those of you who don't know your Greek Alphabet, and have no intuition for the obvious, Greek Kappa is the equivalent of our K today. Thus Kappa Kappa Kappa would be KKK, a term more commonly referring to the Ku Klux Klan.
Boo. (as in disapproval.)
