The 1811 Dictionary of the Vulgar Tongue is a treasure-trove of late eighteenth-century/early nineteenth-century English slang. Francis Grose wrote the first edition in 1785. A very interesting facet of this book is how so many slang words have survived with their meanings basically intact from that time. But be warned, the explanations are clearly from that time period and so can be somewhat difficult to interpret at times. Here are a few excerpts I found enjoyable.

To Box the Jesuit, and Get Cock Roaches: A sea term for masturbation; a crime, it is said, much practiced by the reverend fathers of that society.

Buttock: A whore.

Carvel's Ring: The private parts of a woman. Ham Carvel, a jealous old doctor, dreamed that the Devil gave him a ring, which, so long as he had it on his finger, would prevent his being made a cuckold: waking he found he had got his finger the Lord knows where. See Rabelais, and the Prior's versification of the story.

Cheeser: A strong-smelling fart.

Cundum: The dried gut of a sheep, worn by men in the act of coition, to prevent venereal infection; said to have been invented by one colonel Cundum. These machines were long prepared and sold by a matron of the name of Philips, at the Green Canister, in Half-moon-street, in the Strand. That good lady having acquired a fortune, retired from business; but learning that the town was not well served by her successors, she, out of a patriotic zeal for the public welfare, returned to her occupation; of which she gave notice by divers hand-bills, in circulation of the year 1776. condom

Gentleman's Companion: A louse.

Saint Geoffrey's Day: Never, there being no saint of that name; to-morrow-come-never, when two Sundays come together.

To Screw: To copulate. A female screw; a common prostitute.

To Shag: To copulate. He is but bad shag; he is no woman's man.

Thingstable: Mr Thingstable; Mr Constable: a ludicrous affectation of delicacy in avoiding the first syllable in the title of that officer, which has some similarity to an indecent monosyllable.

Turd: There were four turds for dinner: stir turd, hold turd, tread turd, and mussturd: to wit, a hog's face, feet and chitterlings, with mustard. He will never shite on a seaman's turd; i.e. he will never make a good seaman.

Twiss: (Irish) A jordan, or pot de chambre. A Mr Richard Twiss having in his "Travels" given a very unfavourable description of the Irish character, the inhabitants of Dublin, by way of revenge, thought proper to christen the utensil by his name- suffice to say that the baptismal rites were not wanting at the ceremony. On a nephew of this gentleman the following epigram was made by a friend of ours: Perish the country, yet my name/Shall ne'er be in story forgot,/But still the more increase in fame/ The more the country goes to pot.

Tyburn Blossom: A young thief or pickpocket, who in time will ripen into fruit borne by the deadly never-green.

Well-hung: The blowen was nutts upon the kiddey because he is well-hung; the girl is pleased with the youth because his genitals are large.
