Fun fact: if you hold your poop in too long or have an intestinal blockage that cannot be overcome, it will eventually back up into your stomach and you will throw up poop.
Yeah, itz especially fun because once you start throwing up fecal matter it turns fatal pretty quickly if they a doctor doesnt get you unblocked immediately!
I have had problems with constipation and after I mostly got rid of it, I still often forgot to crap. Nowadays I do my best to crap everyday. When I haven't crapped for a couple days, I'll often shit myself, or suddenly get the feeling that I'll be covered in diarrhoea if I don't get to the toilet within the next ten seconds. But I'm grateful that I never had to experience that.
So the horse is asking Susan if holding poop in for 3 days is unhealthy. Why? And why is Susan upset? She's upset that this is what the horse thinks about and wants to talk about? It's a strange horse for sure.
The last comma should have been a period. For some reason on that particular font the period showed up in the center of the line instead of at the bottom and it looked really weird.
Edit: for what it’s worth, the original meme had a comma too for some reason
