I read this book way back in 1996, and I still pull it from my shelf from time to time. While it is clearly out of date for the newest pieces of sexual slang, it is a goldmine of both archaic and old school terms. If you're not only a word nerd, but a dirty word nerd, you'll love it. I originally purchased it to help me understand some of the slang from Canterbury Tales and did a wonderful job. I now use it to sound like a smarty pants when I do presentations and to discover creative and sneaky insults. This would make a fantastic resource for erotica authors!
