The term 'c-word' is quite useful - appropriate for many western languages. (I won't list them, but if you speak a Romance language you'll be able to recognize yours. ;-))
Incidentally, the harmless rabbit (Latin cunniculus, Spanish conejo) used to have the informal name 'cunny'. Fur made from rabbit skins is still called 'coney' (but not rhyming with money or honey), but the childish word 'cunny' was a bit near the knuckle for the more prudish tastes of the 19th century, so it was changed to 'bunny'. So 'bunny rabbit' is a rabbit rabbit.
