>>513879843 (OP)Ghetto nigger here, there's lots of reasons people live like this that I've seen. I've lived in and around these kind of messes basically all my life.
They can't smell it. Lots of these people live like this because they go "nose blind" (hate that term) and they are so defensive because everyone's a scummy con artist that if you tell them they stink they think you are trying to grift them and spaz out.
There's also just legit mental illness or retardation sometimes. It's like how a dog will piss on a tree, go back and sniff that piss later then be all satisfied like "yeah, that's the smell of my own pee, i'm the boss, i'm the man, i conquer". People who never clean their toilet so it's caked in shit but will go into the bathroom and take a big whiff because it's satisfying on a primal level and not disgusting to them on an intellectual one.
There's an element of monkey dominance to it for some people like a "nobody can make me take a bath, I defy you" kind of mentality. It makes them feel powerful. They're rebelling against society by being a garbage dump.
Magicians, I've met some people who believe that their stench gives them mystical powers rather than be off putting. Guys and girls. Guys who believe that they have better luck with women because of their "musk". Girls who believe they have better luck with men because they don't wash their snatch. There's an element of truth to this, there's a primal attraction to the scent of a man or a woman but to a hygienic person you just smell like a revolting toilet mess.
Some people are just crippled or physically incapable of cleaning but are too proud to admit that or ask for help so they continue living like this to maintain their self imagined identity.
They think there's nothing wrong with it because they are so used to it and think that anyone who cleans is a bougie asshole.
Depression, some people just give up on life and decide to become a huge burden on others.
