We've mentioned before that knowing a few words in the native language can help improve your travel experience. Knowing some of the local slang can help, too — though it's a bit tougher. Natalie Holmes at Conde Nast Traveller lays out local slang for a few major international cities.
The cities covered include Paris, Rome, London, Berlin, Boston and Shanghai. In addition to translations of select words, she also gives useful information about pronunciation and slang background. See the details for yourself by following the link below.
