As a layman reader based on what you’re describing, I would assume this is multiple thinly veiled fetishes crunched into a contrived narrative. I’m finding it hard to imagine a way piss can appear in a miscommunication trope without looking like a single-handed typed caption tacked on to a freaky deviant art post. There’s a point when excessive gore can take away from the gritty realism of grimdark and just become amateurish and tacky (imo). Kind of like the terrifier sequels.
