For all its supposed isolation out there beyond the pale of acceptable discourse — marginal words in the mouths of marginal people — we know a good deal about slang. We know its lexis, and keep chasing down the new arrivals; we know its lexicographers, some very well; we know its speakers, and note that far from monosyllabic illiterates, they coin some of the most inventive usages currently on offer.
Slang—mocking, sneering, casting a jaundiced eye on the world’s proprieties—is by its nature sour. It finds approval hard, congratulation challenging, and affection almost impossible. Yet even if slang’s oldest meaning of “sugar” is money, and the second oldest a euphemism for the most common term for defecation, slang, for all its skepticism, cannot resist the tempting possibilities of “sweet.”
