look up any word, like kappa:
KK - first name of a person. Usually represents the pronunciation of Ancient Chinese characters, such as 嘉家佳加假架嫁.

Just like the sharp sound of "k", the personality of those with name consists the alliteration of "k" is very sharp. They tend to challenge authorities & instead they create and implement the rules they deem appropriate for the mortals. KKs.
k^2, unfortunately, sometimes mistaken to be k^3.

This happens when multiple people call out for KK.
