VERB. To poserize is to make oneself a total and complete
poser in active, organized, and especially PUBLIC fashion. It's a verb so it's a word denoting concerted action of MAKING oneself a complete
poser rather than merely being denoted a
poser by others. To poserize oneself, one must go to considerable public effort. One cannot poserize another person, only oneself. To poserize could be termed the act of not merely appearing as a
poser, but making oneself a poser in public, to the extent that it is self evident and there is no longer a need to call that person a poser, but instead to point out that they poserized themselves.
