It's true that everything old is new again which is why you're once again seeing people wearing KangaROOS shoes. Made famous during the 1980's, these athletic shoes are practical and attractive. KangaROOS footwear is so named because of its trademark zippered pocket that is added to every pair. Like a kangaroo pouch, this pocket is the perfect place for holding onto your keys and other valuables.
Kangaroos are marsupials, a type of mammal that gives birth to undeveloped young.
The young kangaroo, sometimes called a joey, may remain with the mother, climbing into her pouch for nourishment or safety, until it is more than a year old.
Kangaroos are similar to hoofed mammals, or ungulates, such as the deer and antelope, in their ability to digest plant matter that is high in fiber and low in protein.
A kangaroo court is a 'judicial' proceeding that denies proper procedure in the name of expediency; a fraudulent or unjust trial where the decision has essentially been made in advance, usually for the purpose of providing a conviction, either going through the motions of manipulated procedure or allowing no defence at all.
A kangaroo court may be a court that has had its integrity compromised; for example, if the judge is not impartial and refuses to be recused.
Kangaroo court is also used as a derogatory term to describe the dispute resolution mechanism used by prison inmates within the prison, based upon the pecking order of the prisoners.
