I still maintain that slang is good for you, but, sometimes, profanity is even better. Slang is playful and facetious, the story goes, the language by which groups hang together. Profanity, on the other hand, is supposedly coarse and mean. Well, that’s true enough, in some cases, but I’ve recently been reminded that profanity is occasionally the lighter alternative, that the relevant slang is what’s coarse and violent. Yes, I’m talking about sex, or, more precisely, the language of sex — not copulate or get it on, but the relative value of fuck and bang or nail.
