Cager is the common name of the species Doofus Automotivus Oblivious . Common characteristics are, short attention span, poor judgement, and lack of a clue. They wrap themselves in metal boxes or cages which leads to a false sense of security & invulnerability. Cagers have been known to prey on bikers ( Moto Insanus Rapidi ) pedestrians ( Shank's Mare Perambulus ) and even other cagers. Cagers are rendered less harmful with liberal applications of vigilance, foresight, and talent.
