I think you mean "cojones". With an "o".
I predict that the English language will, in the next decade or so, acquire a new word, “cajones,” pronounced “Cah-Jones” or perhaps “Cay-junz,” like the French-speaking Louisiana population. It will be used by certain people to refer to their testicles.
To clear it up for everyone, they haven’t got a “pair” among them.
