Rude Spanish: An Alternative Spanish Phrasebook

"Rude Spanish" is a highly entertaining book covering European Spanish only (that is to say, it does not cover Latin American varieties of slang). Although it is very amusing and contains some great information and words, it's usefulness is somewhat limited as you are unlikely to ever find yourself in the scenarios featured in the book. A good little novelty book to purchase if you're heading to Spain and you'd like to have a brief idea what people are on about, but there are better alternatives with a much broader scope available.
