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.
“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.

14. PULLY HAWLY
A game at pully hawly is a series of affairs.
