17 Euphemisms for Sex From the 1800s

While shoe-horning these into conversation today might prove difficult, these 17 synonyms for sex were used often enough in 19th-century England to earn a place in the 1811 Dictionary of the Vulgar Tongue, a book for upper-crust Britons who had no idea what members of the lower classes were talking about.

1. Amorous Congress

To say two people were engaged in amorous congress was by far the most polite option on the list, oftentimes serving as the definition for other, less discreet synonyms.

2. 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.

3. Bread and Butter

As the 1811 Dictionary of the Vulgar Tongue puts it, this refers to one person on top of the other. "Rumor has it he found her bread and butter fashion with the neighbor."

4. Brush

"Yeah, we had a brush once." The emphasis here is on brevity; just a fling, no big deal.

5. Clicket

"They left together, so they're probably at clicket." This was originally used only for foxes, but became less specific as more and more phrases for doing it were needed. One definition from the 1811 Dictionary of the Vulgar Tongue maintains the term’s original outdoorsy nature: “the man and woman are copulating in the ditch.”

6. Face-Making

Aside from the obvious, this also comes from "making children," because babies have faces.

7. Blanket Hornpipe

There is probably no way to use this in seriousness or discreetly, but there you have it.

8. Blow the Grounsils

"Grounsils" are foundation timbers, so to have sex on the floor.

9. Convivial Society

Similar to "amorous congress" in that this was a gentler term suitable for even the noble classes to use, even if they only whispered it.

10. Take a Flyer

"Flyers" being shoes, this is to have sex while still dressed, or “without going to bed.”

11. Green Gown

Giving a girl a green gown can only happen in the grass.

12. Lobster Kettle

A woman who sleeps with soldiers coming in at port is said to "make a lobster kettle" of herself.

13. Melting Moments

Those shared by "a fat man and woman in amorous congress."

14. Pully Hawly

A game at pully hawly is a series of affairs.

15. Riding St. George

In the story of St. George and the Dragon, the dragon reared up from the lake to tower over the saint. "Playing at St. George" or "riding St. George" casts a woman as the dragon and puts her on top.

16. A Stitch

Similar to having a brush, "making a stitch" is a casual affair.

17. Tiff

A tiff could be a minor argument or falling-out, as we know it. But in the 19th century, it was also a term for eating or drinking between meals, or in this case, a quickie.
