Armchair psychology/art theory incoming~~~
Thesis: Toilets are a popular motif in vkei and other edgy art circles because they represent the yucky sides of humanity: bodily functions (yucky!), violation of privacy/voyeurism, and the SEX.
Postulate A: Toilets are a place for urination and defecation, traditionally viewed by many cultures as dirty. They are places that are naturally going to be filled with unsavory smells and are therefore unpleasant to be in, but are 100% natural and necessary parts of being humans. We don’t even like TALKING about pooping and peeing, let alone hanging out where it happens.
Postulate B: Toilets are private, vulnerable places. During the act of defecation/urination, we expose very sensitive areas of our bodies and are in vulnerable positions (since you usually can’t exactly get up and run away suddenly in case of a threat appearing) Therefore, this has naturally evolved into a desire for privacy and shelter during the act. The idea of being trapped and watched by someone while on a toilet is very uncomfortable for most people, and the idea of watching someone using one in a voyeuristic way also feels very taboo.
Postulate C: In the toilet, we expose our genitalia. Many cultures around the world demand the covering of bodies in public to prevent inappropriate sexual desires from arising. Bathrooms are one of the few public spaces where bodies are fully exposed (albeit in an enclosed space). Men’s bathrooms especially are not fully private, therefore technically creating a shared space of public nudity that can be sexually exciting for some people. There is also the modern phenomenon of bathroom quickies.
Therefore, I hypothesize that bathrooms are literally and socially “unclean” spaces, and by posing in one, the artist suggests an culturally “unclean” identity or theme.
