Zo-wow-u-doin? > Question concentrated into one word. ie, So how are you doing?
Living in Brooklyn, wannabees take the liberty of starting a typical greeting or conversation with the abbreviated version of "so how are you doing?"
this is usually followed by 4 quick goods (good, good, good ,good). If you get 2 goods (good, good) he usually has something on his mind and the proper response should be wassamatta? if you get the 4 goods then revert back to zowowudoin? after about four go arounds you can consider it a nice interaction with your fellow brooklynite.
