In that context, it comes from “crunchy granola”, aka the sort of hippie/hipster that tends to embrace that kind of trendy natural diet. Granola entered the hippie sorts back in the sixties and the terminology came around somewhere in the mid seventies to early eighties.
By the time I was in my teens, it was in use for those retro-hippie sorts that also tended to the more idealized parts of hippiedom. Those kids are now the uncles and aunts (and sometimes even grandparents or great aunts/uncles) referred to.
In that specific context, adding in the aunt/uncle part, it is a positive. However, it’s also a tad condescending, if unintentionally so. That those aunts and uncles are something that needs an extra label to lump them into an outside group is often done because the person doing the lumping thinks they’re better.
Truth? Some of the crunchy granola sorts are dipshits. They’ll eat “natural” even if it isn’t actually healthy. They’ll rattle on about stuff that nobody else present cares about not because that’s who they are, but because they’re evangelizing. So some of the reputation for being hippie-dippie if you’re also crunchy granola is deserved. Same with being a skeevy stoner hippy being often linked to the other labels.









I’m pretty basic. Van Gogh is top for me.
Mind you, Gonsalves ranks right up there along with Magritte and Monet.
I reckon you can guess what “schools” I tend to respond to most lol
