Preposturize . . . A Preposterous Neologism

According to Google (who is all-knowing in such matters) the word "preposturize" does not exist in the English language.  I hereby declare my intention to, and herein do, lay claim to this bit of intellectual real-estate.  "Preposturize" shall henceforth and forevermore be defined as a verb, whose meaning is to extemporize preposterously; i.e., "The presidential candidates preposturized at the debate last night."  See also, "preposturizement," and "preposturizingly."
