Hello, Oddipus. Actually, the word
cojones(pronounced
cohones) is Spanish, and yes, its a slang for balls.
Kahonee, or Kahuna, is an hawaiian word for shaman. A big kahuna is the greatest spiritual leader of hawaiian culture, and it has nothing to do with
big cojones(except that a big Kahuna has to be a guy with big cojones,
)
