A flashpacker is a backpacker who travels in and out of towns, cities or countries in short periods of time. Typically a flashpacker spends 2 to 3 days in each location as they try to squeeze as many places into one trip, rather than stay in one place for a longer period of time gaining a deeper appreciation for it. Therefore you are in and out in a flash.
