The dictionary of Spanish Slang, common to most if not all similiar books, attempts to cover sland accross the spanish speaking world, it is presnted in a simple dictionary format alphabetical by spanish slang words, so working back from english is all but impossible, and finding words with a similiar meaning would involve some heavy browsing.
unfortunately this type of browsing dictionary suffers because its difficult to quickly get to slang for the region wanted without finding and discarding slang from other regions.
Having only used this book in peninsula Spain, i would say that i have found the listings very incomplete, much of the common slang heard in spain is completely absent. possibly better for latin america.
