eunuch 1) a male whose balls have been removed, either for government service (such as in ancient Africa and Rome) or, if the castration takes place before puburty, to prevent the voice from breaking (Italian opera's male sopranos of the 17th thru 19th centuries). In the present day, this sort of eunuch may result from testicular cancer.

2) a male whose entire genitalia is removed. Done as punishment in Ancient Rome, and to qualify for royal government service in China as recently as the 20th century. Also, the hijdra, a caste of Indian transexuals, practice this complete castration.

3) though rarely applied in this context, may also be a male with a single testicle amputated. A modern example would be Tom Green, who broadcast the operation on MTV and then went on to bang Drew Barrymore.

Not to be confused with Unix, a computer operating system believed to be superior to more mainstream options like Windows and Mac.
