Cottagecore is an Internet aesthetic which celebrates a return to traditional skills and crafts such as foraging, baking and pottery, and is related to similar nostalgic aesthetic movements such as grandmacore, farmcore, goblincore and faeriecore.
Who am I to judge? But I just don't know man! It seems to me their could call it "Post Art and Crafts" or Nouveaupunk and be done with it. Faeries? Art Nouveau. Pottery? Arts and Crafts. Grandmacore?? Really? I'd call it Babushkapunk. The words "core" and "grandma" don't belong in the same sentence! It's just an alphabet soup of terms...
