To take a long trip, often through a dangerous area (e.g. ghetto, Wal-Mart) to get back homeward. Named after Greek
historian Xenophon's Anabasis (The March Up Country) where 10,000 Greek
mercenaries had to escape back to Greece after their leader was killed.
Stan and me had to go on an Anabasis to get back to the
Food Court after losing James to the
Hot Topic Vampires.
