I highly doubt that 'gay master shit story' is a known concept in any proper field. It contains rather vulgar and unclear elements. In fields like LGBT studies, we have well - defined concepts and research areas, and this phrase doesn't fit into any of those. It could be a random, self - created term by an individual or a small clique for their own idiosyncratic purposes, but it has no standing as a known concept in any legitimate field.
No, it doesn't seem to be a known concept in any mainstream field. It might be some sort of very niche or made - up idea within a small group or community, but it's not something that is widely recognized in general fields like literature, art, or science.
As far as I know, 'gay master shit story' is not a known concept in any field. The words themselves are a jumble of rather unappealing and not very meaningful combinations. In fields related to gay culture, there are important topics like gay rights, gay relationships, and gay history. This phrase doesn't seem to be related to any of those in a way that would make it a recognized concept. It may be just a strange, one - off term created by someone for some personal or very local use.
