Hippie Parents

The Seventies are far back enough now that a lot of those people who were living the hippie lifestyle are now parents or even grandparents, so you can bet that they show up a lot in fiction. They are pretty easy to spot, they usually live in a house with an astonishingly orange and brown decor ripped directly from the 70s even though it's the 2000s, enjoy cannabis, still wear seventies clothes, and sport seventies hair styles, say things like 'groovy' and name their kids embarrassing things like 'Flower' or 'Rainbow'. They often double as Amazingly Embarrassing Parents, and engage in Hands-Off Parenting. May or may not have once lived in a Hippie Commune, but they probably have some crazy stories that are bound to scar their children for life.

Compare Hippie Teacher. A subtrope of New Age Retro Hippie and Bourgeois Bohemian. Contrast The Vietnam Vet Father, who usually grew up in a similar time period but went completely the other way about it.
