A former hippie with sterotypical beliefs, who may or may not still externaly show their hippiness, and have liberal beliefs. This phrase was coined on an episode of South Park. An example of a possible aging hippie is a man in his late fifties/early sixties, afull beard, but groomed, long strait hair, usually braided or tied into a pony tail, and openly speaks out their beliefs in the way of an activist.
Oh God, here comes that aging hippie liberal douche, we better get out of here before we have to hear his bitching.
