Admit it: what is the language skill you really need while abroad? It's not finding out how to get to the zoo. You want to be able to blaspheme like a native. How to Swear Around the World ($13) will teach you how to do exactly that in dozens of different languages. Tell new friends what you really think of their grandmothers, ask strangers if they just had relations with a mule, or wish surly waiters a painful and humiliating death.
