There are a number of difficulties with dirty words, the first of which is that there aren’t nearly enough of them; the second is that the people who use them are normally numskulls and prudes; the third is that in general they’re not at all sexy, and the main reason for this is that no one loves them enough….
Thin in content, few in number, constantly abused: what chance do the unspeakables have? Change is resisted fiercely, additions are denied. I have introduced ‘squeer,’ ‘crott,’ ‘kotswinkling,’ and ‘papdapper,’ with no success. Sometimes obvious substitutes, like ‘socksucker,’ catch on, but not for long. What we need, of course, is a language which will allow us to distinguish the normal or routine fuck from the glorious, the rare, or the lousy one—a fack from a fick, a fick from a fock—but we have more names for parts of horses than we have for kinds of kisses, and our earthy words are all . . . well . . . ‘dirty.’ It says something dirty about us, no doubt, because in a society which had a mind for the body and other similarly vital things, there would be a word for coming down, or going up, words for nibbles on the bias, earlobe loving, and every variety of tongue track. After all, how many kinds of birds do we distinguish?
