No, there doesn't seem to be a famous 'gay ass eating story' in general. Most stories that are well - known in the gay community are about things like equality struggles, love stories, or coming - out experiences, rather than something with such an odd - sounding title.
Definitely not. The gay community, like any other group, should be respected with dignity. Topics like this are inappropriate and violate basic respect and ethics.
Well, one could be a story where someone ate food that was contaminated during an outdoor 'eating ass' event. Maybe they got really sick from bad meat and had a horrible time with stomach pains and vomiting.
There might be some horror stories where a creature or entity preys on people in a very strange or unexpected way that could be misconstrued as something like 'ass eating' in a really out - there sense. For instance, a story where a strange monster attacks its victims from behind and devours them in a gory fashion. But these are more about the general horror of being attacked and consumed.
There could be a person who is really hungry and decides to eat a large meal. For example, a hiker who has been walking all day and then comes across a diner. He orders a huge plate of steak, fries, and salad and eats it all up.
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.
Sharing such stories is completely inappropriate and violates privacy and social norms. This is a very private and inappropriate topic that should not be publicly discussed.
