FARANJI FRENZY (NOUN): the shouts of "You! You! You! You!" which raise the hackles of of travelers (Faranji); it can also take the form of screaming, giggling, shouting, or snickering children. Like begging, there is no clear response. Ignoring it, or, even better, treating it with humor is probably the best answer. If you're waiting for a bus and become a captive spectacle, trying to communicate with locals usually breaks the animal in a zoo feeling. You may just transform the howling mob into delightful and charming individuals. Although you're never likely to get used to faranji frenzy, at least feel thankful that it's almost never aggressive or hostile.
