PUSSY. This Anglo-Saxon term is intriguing because it has a double derivation from two Old Norse-Old German words: “puss” meaning cat, and “pusa,” meaning pouch. As far back as etymologists can go, “puss” meant cats, and women were poetically equated with them.
Even today, Kat and Kitty are common nicknames for Katharine, and a woman who makes malicious remarks is “catty.” So it’s not difficult to imagine how “puss” evolved from a term for soft, furry little
pets into a word for the soft, furry place between women’s legs.
At the same time, “pusa” evolved from a term for pouch into one that connoted pouch-like anatomical structures, initially, the vaginas of cows and mares, and after a while, the human vulva-vagina.
According to the Oxford English Dictionary (OED), the first printed reference to “pus*y” in a sexual context was a bar-room toast from 1664: “Here’s good health to thee, good company, and good pus*y.”
