A term popular in Japan. It describes a cute girl who is not necessarily plus size, but doesn't fit the skinny stereotype of Japan (and pretty much the rest of the world).
La Farfa magazine is a pioneer of featuring Marshmallow Girls. Their models usually weigh between 60 - 120kg (about 130-230 lbs).
Here is a quote from their editor-in-chief:
“We don’t promote losing weight or gaining weight, because there are women that look gorgeous regardless of what they weigh...Our view is that people should not be defined by the size of the clothes they wear."
Marshmallow Girl Goto Seina is so cute!!
A mama's girl.
The marshmallow girl thought the world owed her the kind of support her mother gave her as a kid.
The kind of female that thinks nobody can straighten her out.
The marshmallow girl looked and sounded serious in her 30's, but she was as silly as they got as a kid, and people don't really change, their nature remains the same throughout their lives, no matter how old they get.
A mama's girl.
The marshmallow girl thought the world owed her the kind of support and respect her mother always gave her as a kid, back when she was her mother's little baby.
A girl that is about as hard as a marshmallow.
The marshmallow girl didn't think the world supported her enough, but if they did, she thought any kindness she was shown shown by them was weakness on their end. She also thought that because she never got an ass whooping from an authority figure such as a parent as a kid, that there was nobody in the world that could do it.
