Rejuvenile is a cultural redefinition to what "adult" means.  The pipe-smoking dad and mother baking in her pearls are obviously out-of-date images.  Yet we still hold similar irrelevant ideas of adulthood as expected norms.  The rejuvenile trend is a resisting to this ill-fitting social expectation, and a revisiting to fun.  Because 50 can be as entertaining as 20, just with trinkets and Viagra.  They're the Peter Pans of our day, taking a stand and saying, "I refuse to be your idea of an adult."  And I've got quite the posse of Lost Boys—and Girls—backing me.
