two Cs in a K
n.— «If all this sounds like the ad industry is still rooted in a sexist world that the rest of us have left behind, then remember that not that long ago there was a standard adland shorthand for an entire genre of advertising known as two Cs in a K (the long hand of which translates as two c**ts in a kitchen). Ad after ad after ad followed the formula because everyone understood it and it was extremely effective. We bought what the Cs in the K sold.» —“Cars for boys, chocolate for girls” by Claire Beale Independent (United Kingdom) May 25, 2009. (source: Double-Tongued Dictionary)
