"Two c's in a k" (short for "two cunts in a kitchen") is slang used within the advertising industry for a type of advertisement, generally showing two women in a domestic scene, discussing, using, or otherwise portraying the advertiser's product in a positive manner. The term was used by Madison Avenue advertising executives in the 1980s.
This method has been typical for advertising targeted at women, such as television commercials for household cleaning products, personal care products or feminine hygiene products, such as a 1959 advertisement for Pursettes tampons which depicted two women discussing tampons over coffee. Special tutorial marketing films for the salesmen and marketing staff only featured actresses displaying exactly how to apply tampons and other feminine products.
