look up any word, like blumpkin:
itour or I-Tour is an emerging genre in the travel/tourism market making use of mp3 audio files to create tours of destinations, cities, and attractions. The "iTour" is purchased then downloaded to iPod, mp3 player, or smartphone for convenient playback. iTours exist in cities such as New York NY, Savannah GA, San Francisco CA, London, Rome, and Phladelphia PA among others.
