kahunas n.pl. testicles; cojones. Also kahoonas. Editorial Note: Can be used in all the same ways as other slang terms for “testicles.” This kind of transformation of a Spanish word into substantially different Anglicized spellings, which in turn represent a different pronunciation, is a sign of its nearly complete adoption into English. There may, however, be some confluence with kahuna ‘a powerful person or leader,’ especially in the common form big kahuna. Mark Liberman at Language Log has written more about cojones/kahuna. Etymological Note: From the Spanish cojones ‘testicles.’ (source: Double-Tongued Dictionary)
