There could be many interpretations of such a phrase. Maybe it's about some comical or absurd situations where things go wrong in a very extreme way. But again, without clear definition, it's just speculation.
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 young artist might have cocked up her first big art exhibition. Maybe some of her paintings didn't turn out as she hoped, they seemed 'hard' to look at in terms of the result she desired. But she took the criticism well and used it to improve. She experimented more and now her works are much better and well - received.
Since the phrase is so ambiguous, it's hard to come up with examples. If 'cock up' means to mess something up in a big way, perhaps it could be stories about big blunders in business or projects that had really bad consequences, but this is just a wild guess.
Another story could be about a young athlete. He cocked up his big race by not warming up properly. His legs felt like they were made of lead (hard) during the race. He was really disappointed in himself. But instead of giving up, he worked on his pre - race routine and became more successful in future races.
However, if "granny cock" is some sort of made - up or very specific local term, it's really hard to know exactly. It could also potentially be part of a cultural or regional folklore that we are not familiar with. We would need more details to accurately share the stories.
This is a rather vulgar and inappropriate expression. If we break it down literally, 'cock' can refer to a male chicken or be a vulgar term for a male sexual organ, and 'up my ass' is an extremely inappropriate and vulgar description. But it's not a phrase that should be used in polite or general conversation.
No, it's not a common phrase at all. In normal English usage, it seems rather strange and not a typical expression you would hear in everyday conversation or see in general writing.
There are many heart - warming stories about grandmothers in literature and real life. They might be about how a granny passed on her wisdom, like teaching her grandchildren how to sew or knit, or stories of how she overcame difficulties in her life and inspired the younger generation with her perseverance.
