Is there a psychological profile associated with this type of habitual behavior? What the heck makes someone want to poop on someone's lawn or in public? I'm genuinely curious. I could never, unless it was a situation of being so extremely sick that I just couldn't make it home but even then, to pop a squat and poop on somebody's lawn just seems to weird to me. Does she even bring toilet paper with her?
It's not a profile, per se, but people with dementia/Alzheimer's or any range of severe psychological problems, or simply anybody whose mental state has been altered somehow (like acute encephalitis, I guess???) tend to poop in inappropriate places, or try to eat feces, or smear it on themselves, the walls, the furniture, be it on purpose or unknowingly.
I don't have any more info for you than that. I was a CNA and was warned of it in training. Fortunately I only had to handle a case of this behavior once, and it wasn't all that bad because the cleanup was easy. The smell lingered though. I won't get into it for the sake of the patient's dignity.
Idk, brains are weird and fallible. Even a severe fever can trigger this kind of thing.
Edit: I want to make it clear that this isn't always the reason for public defecation. Some people might have something else going on, be it a bowel issue, or such a strong dislike of a neighbor or business and the ability to detach from their shame long enough to make their hatred known, lol.
Personally, I couldn't do it, assuming I was in a normal mental state. Not even if I was guaranteed no witnesses or cameras. I wouldn't even pull over to do it on the side of the freeway. I just couldn't. I'd be far too mortified.
