Bat shit is pretty toxic, and while individual poo is small, bat colonies are absolutely massive and the shit literally piles up as up to millions of bats poop in the same place night after night.

Bullshit is meaningless talk or meaningless tasks.

Horseshit is a falsehood.

Batshit is crazy or deranged.

Dogshit is something low-quality.

The bat shit I've run across is absolutely the worst smelling thing I've ever run across. Similar experience to a rotting whale carcass

I mean... It's poop. Why would there be positive connotations? lol

Horses, because they used to be everywhere. Step in the street, and you were likely to step in some.

Bull, because it’s very big and smelly and there was usually some around (steer manure is still prized for gardening).

Bats… because it rains from above and is really gross, and you’ve got a high likelihood of getting really sick from it.

Why we don’t go on about pigeon and seagull guano though? I have no idea.

Bat poop is associated with COVID-19, Ebola, and Marburg viruses.

It isn't just those, but horses and bulls have the biggest poops most people will ever see. So using them as reference for giant piles of unpleasant things makes sense.

Now, batshit? For one, have you ever been near where bats stay? The smell is so fucking intense.

But, bats are also known to flit around in a way that's erratic when you rarely see their entire flight path. So they have a reputation for being less predictable, or a little crazy. At least that's my understanding of how bats got referenced for someone being easily distracted, weird, or crazy. You know, "that old lady is a little batty, so don't be surprised if she forgets to pay you", or "that dude has bats in his belfry".

How that got linked too batshit, I'm not certain. Back when I looked it up, the sources we have now didn't exist., which ima go look the etymology of it up and see if there's something newer to me. If there is, I'll come back.

Nah, nothing new. Only thing that I saw this time was batshit probably coming more as a variant of bullshit, with a similar meaning, and then getting tangled up with the idea of being batty. So, in terms of how it would be used, a crazy person isn't bullshitting because they think what they're spewing is true, so it's batshit instead.

Also, I noticed apeshit out there as well. Meaning to lose one's shit in a violent way. Which, apes tend to look like they're going apeshit as a dominance/threat display, but tend to not carry through as often as humans do

Bat and bird poop can carry diseases such as histoplasmosis.

shit sucks

I love cow dung smell (when it's not too much of it) - it reminds me of childhood, summer, riding my bike through the fields, etc. Rural stuff.
