Strike a light! British Airways has compiled an online dictionary of London slang to help American tourists and ex-pats blend in and feel at home. Although Londonist can think of few more conspicuous things than an American tourist casually attempting to slip the words "tickety-boo" into conversation.
This lexicon runs to 80 words, including "minger", "afters", and "beer mat", and BA claims it is the first of its kind, which Londonist frankly finds very hard to believe. A good laugh or intensely patronising? It's very hard to decide.
