Cojones (s. cojón [ko'xon]) and huevos (eggs) are vulgar Spanish curse-word usages for testicles. The singular form, cojón contains the augmentative suffix -ón (implying magnitude), and derives from the Vulgar Latin coleonem, the accusative form of coleo (testicle), an augmentative form of cōleus (leather bag for liquids); its variants are cūleus and culleus.
