An overpriced hotel run by arabs, or other middle eastern peoples. Usually very dirty, sometimes used as a money laundering front for terrorist organizations. It is advisable to wear a chemical jimmy when occupying an econohaj, if only to keep space herpes from infecting you via airborne means.
econohaji usually rely on sabotage as a means of attracting prey. I.E. posting "proud to be an American", "American owned", "I hate all my cousins too", or "No hezbollah here" signs on all windows visible by the public.
I planed on staying at a mom and pop place since I couldn't afford the Hilton, but I booked online and wound up in an econohaj.
