You might enjoy this book. It’s like dictionary of random slang words from around the world, with different chapters based on categories.
Personally, I was a little disappointed because 99% of the definitions are just one sentence or sentence fragment. I was hoping to find out a little more about the origins of more of the words and maybe a little of the culture behind them.
I love that website. I’m considering getting the printed volumes to support them, even though I’ve read most of the articles already.
