The bushy tail also inspired words for "fox" in Welsh (llwynog, from llwyn "bush"); Spanish (raposa, from rabo "tail"); and Lithuanian (uodegis, from uodega "tail"). Metaphoric extension to "clever person" was in late Old English. Meaning "sexually attractive woman" is from 1940s; but foxy in this sense is recorded from 1895. A fox-tail was anciently one of the badges of a fool (late 14c.).

It also recommends, for sexual intercourse without irritation, "the extremest end of a foxes tail hung upon the arm." Rubbing a fox's testicles on warts was supposed a means to get rid of them.

As a variation of the one-step, as a legitimate successor to all the objectionable trots, the fox trot has attained a form which is in a fair way to become permanent. ... It has the charm of being an absolute fit for many of the most alluring transient tunes; and it can be danced, without self-consciousness, by hundreds of people who never pretended to be graceful or dancefully talented.
