Hooroo
An Australian way of say goodbye. Originates from the practice of lonely guys out in the bush, who after meeting and talking of their plight would often say goodbye before going off to "Hoo a Roo". Roo is a shortened name for the Kangaroo and Hoo comes from the sound said Kangaroo makes when surprised from behind.
Guys would say "Time to Hoo a Roo" on parting and this gradually became shortened to Hooroo.
