Gookasaurus

A title that is only given to an individual that has transcended all levels of douche and doofus, and can only be described with the word "Gookasaurus". Gookasaurus can only be attributed to those whose levels of douchebaggery cannot be describe with a rational word. The first time that this term was used in recorded history was to describe former australian prime minister Kevin Rudd.
