Readers of historical romance tend to think of the Georgian and Regency periods as being as prim and proper, in terms of women's language, as the Victorian period. In fact, the 1800s were a much looser and more ribald period, in which women appear to have freely enjoyed all kinds of bawdy jokes. Here's one published in the The Rambler's Magazine; or the Annals of Gallantry, Glee, Pleasure, and the Bon Ton, etc (1783-90):

A gentleman happening to make water against a house, did not see two young ladies looking out of a window close by, till hearing them giggling, when looking toward them, he asked, what made them so merry. "O lord," said one of them, "a very little thing will make us laugh."
