The Persian language possesses a robust inventory of profanity ( fohsh ), much of which derives from the semantic fields of genitalia, sexual acts, and bodily functions. Among these, kos o kon kardan stands out because its literal components— kos (vulva/cunt) and kon (present stem of kardan , "to do," but also a noun meaning "fucking" in this compound)—combine to form an idiom that rarely describes actual sex. Instead, speakers use it to denote .

The origins of Kos O Kon Kardan date back to the Qajar era (1789-1925), when Persian cuisine began to flourish under the patronage of the royal court. During this period, chefs from across the empire experimented with new ingredients, techniques, and flavor combinations, leading to the creation of innovative dishes like Kos O Kon Kardan.
