The Atlantic has a nice list up of 19th century British slang for "sex." Here are the best ones:
- Amorous congress:To say two people were engaged in the amorous congress was by far the most polite option on the list, oftentimes serving as the definition for other, less discreet synonyms.
- Basket-making:"Those two recently opened a basket-making shop." From a method of making children's stockings, in which knitting the heel is called basket-making .
- Bread and butter:One on top of the other. "Rumor has it he found her bread and butter fashion with the neighbor."
Aside from the obvious, this also comes from "making children," because babies have faces.
- Blanket hornpipe:
- Green gown:Giving a girl a green gown can only happen in the grass.
- Lobster kettle:A woman who sleeps with soldiers coming in at port is said to "make a lobster kettle" of herself.
