The first chapter is a a four word sentence, referring to the observation that the truly shocking words in a language tend to fall into one of four categories,
"Looking just at English, you’ll find that nearly all the most profane words in Great Britain, New Zealand, and the United States fall into one of these four categories: praying, fornicating, excreting, and slurring. "
Cantonese has five words widely agreed upon as the most vulgar in the language—these are the words censored on broadcast television in Hong Kong.10 They are diu (“fuck”), gau (“cock”), lan (“dick”), tsat (“boner”), and hai (“cunt”). If you’re keeping score at home, that’s five for Fucking.
Or consider Russian. Ripped from the censor’s press sheet is the official list of the most profane Russian words, currently banned from movies, plays, and other forms of art.11 The strongest profanity in the language, known as mat’ , has two tiers. The top tier houses the four most profane Russian words: two words for genitalia, a word equivalent to fuck , and a word that translates as whore . Including the second tier of somewhat outdated and weaker profanities, mat’ totals eleven words: seven for genitalia, plus two for sexual acts and two for categories of people who engage in stigmatized sexual acts (prostitutes and homosexuals). In sum, two slurs and the rest are related to sex.
Finnish, which is unrelated to Russian and Cantonese (or to English for that matter) paints a similar picture, at least based on accounts provided by linguists. The top Finnish profanities are words roughly equivalent to hell, God, cunt, piss, shit, ass, fuck , and a number of words roughly translated as cunt or cock .12
French prays. This is Quebecois, which isn’t real French but whatev.

I think the author is on record that contemporary American English slurs. It used to fornicate and excrete, but tastes change.
Some cultures have taboos surrounding death, so there may be a fifth category.
