Lili Loofbourow gets her hands on a 1656 pamphlet called the Academy of Pleasure:
As a lady, your 'sack' might be tickled by someone's 'Bloody Great Kidney Wiper,' or you could welcome a rolling pin into your treasure. Parts shuffle and recombine in circumvolutory spirals: her 'ruff' to his 'sweepstakes,' his bilbo to her wheel. You could explore her terra incognita with your Robin. Invite his spoon into your tub. Mock a man's rouncival, ride his rope, diddle his distaff. … The words refer to the parts we know, but just as there are nights when a lady's ruff drives you wild, there are nights when it's just a sack. Same goes for rouncivals and spigots.
