The Yanomamö, like anthropology subjects everywhere, regarded the note-scribbling scholar as a choice target for practical jokes. Only after months of effort did Mr. Chagnon learn that his informants had been deliberately feeding him bogus names. Naturally, he found out in the most humiliating way possible: Telling a group of men something about a headman's wife, he unknowingly referred to her by a capillo-vaginal epithet.Even if you knew the meaning of capillo- ("hair"), the intended epithet might not be immediately apparent. (Me, I was led astray by thinking first of capillaries.) Luckily Google Books will show you the page with Chagnon's actual words:
Apparently the WSJ's rules for taboo avoidance allow for a cuteness factor; I don't think the New York times would find "capillo-vaginal" amusing enough (or, perhaps, obscure enough) to pass muster as printable euphemism.
