Where does duck butter come from?

The term duck butter is older than you may want to believe. In the 1930s, it was slang for semen, and in the 1950s, smegma. The duck may refer to the smell of duck droppings, according to Green’s Dictionary of Slang, and the butter, its liquidness and light color.

While use of the word continued into the 1990s, the senses of duck butter admitted a new and more common one in the early 2000s: sweat in the crotch, usually under a male’s scrotum. Other definitions add anal and vaginal secretions, not unlike its slang cousin truffle butter. Sex isn’t the only source of these fluids: exercise, hot temperatures, and excessive seating may form the quacky (but natural) lather.

The 2018 romantic comedy Duck Butter took advantage of the slang. It follows two women (Laia Costa and Alia Shawkat) who are determined to have sex every hour, on the hour—the prolonged sexual activity apparently churning up some serious duck butter, among things (like emotions).

The categorically good things about Duck Butter are: 1) The sex scenes, which feel real and are not male gaze-y in any way; 2) the fact that the screenplay was co-written and the film was executive produced by Shawkat, an actual queer woman; 3) Shawkat’s performance. She’s a star; and 4) There are moments of real intimacy; most importantly, Naima’s recounting of a sexual experience that leads to Sergio explaining the concept of “duck butter” to her.

Who uses duck butter?

While both men and women are said to get duck butter, the term is more closely associated with—how do we put it?—ball sweat.

That association bewildered some over the choice of the term as the title for the 2018 film.

But as with many sexual slang terms, duck butter sounds innocent enough, which means class clowns seize on it for some jokes.
