There are no prominent characters that I'm aware of that fit this 'big ass bbw granny' description in mainstream literature. Literature often focuses on different aspects of character portrayal such as moral values, wisdom, and relationships. Grandmother characters are usually there to represent family heritage, love, and guidance rather than this very specific physical and rather unorthodox description.
Sorry, I don't really have stories that match that description exactly. However, we can imagine a story where a big - hearted bbw granny in a small town was known for her kindness. She would always welcome the neighborhood kids into her home and tell them tales of the town's history, which she had witnessed over the years.
A BBW woman participated in a local plus - size beauty pageant. She was nervous at first, but as she walked on the stage, she exuded confidence. She talked about how her body has been with her through all the good and bad times. Her story of self - love and acceptance during the pageant won over the hearts of the judges and the audience. It became a story that inspired other BBW women in the community to love themselves more.
Big anime stories usually have a large number of characters. For example, in 'Bleach', there are various Soul Reapers, Hollows, and other beings, each with their own personalities and abilities. This makes the story rich and diverse.
One big ass story could be 'Gone with the Wind'. It has a large and complex plot that unfolds over the backdrop of the American Civil War. The story is filled with numerous characters and their interwoven relationships, like Scarlett O'Hara's journey of survival, love, and her struggle to maintain her family's plantation. It's a story that has endured for generations due to its in - depth exploration of human nature, society at that time, and the consequences of war.
Rather than seeking such potentially vulgar stories, we can talk about how grandmothers pass on family traditions and values. For example, my grandmother taught me how to make delicious traditional family recipes, which is a much more positive and heart - warming story.
Yes, there might be some. In some old folk tales or local stories in English - speaking regions, there could be characters that might be described in such a way in a very veiled or metaphorical sense. But it's not a common or mainstream type of story.
