If 'trouser snakes' is a euphemism for snakes that are found in a trouser - like environment, perhaps in a jungle where people are wearing trousers and encounter snakes. But this is just speculation. There's no common known set of stories with such a strange term without more context.
I'm not entirely sure as 'belly bulge fanfic' could refer to a very specific type of fan - created fictional work. It might be related to stories that focus on the concept of a belly bulge, perhaps in a body - positive context, or it could be part of some niche fictional genre that I'm not familiar with.
Well, 'gay kissing the bulge fanfic' is likely a form of fan - created fictional writing. 'Gay kissing' refers to romantic or sexual interaction between two male - identified individuals. The 'bulge' part is a more sexualized and perhaps inappropriate reference. But generally, fanfic often takes existing concepts or characters and spins them into new, often unorthodox stories.
A 'belly bulge' could be described in a fanfic in relation to various things like a character being overfed in a comical or strange scenario, or maybe having some sort of internal condition that causes it. But the 'forced' aspect makes it a bit more complex. If it means forced into a situation that causes the belly bulge, it could be part of a dark or unethical plot in the fanfic, which is not something that should be promoted. Fanfic should generally be positive and based on consensual and ethical storytelling.
I'm not aware of any specifically popular 'belly bulge fanfic' works. It seems like a rather niche topic, and not something that has a mainstream following in the general fanfic community.
There's no way to know for sure if Tanner Braungardt is aware of this 'bulge fan fiction'. He may be completely oblivious to it, especially if it's a very niche or underground form of fan - created content.
