I took the nastiest shiit of my life and idk why

I felt totally normal then I looked at some spaghetti and my stomach started bubbling i went to fart but i felt a shart coming on so my b hole tensed up and started burning like hell, i didn't know what to do so i went to the toilet and straight liquid came out with some solid shiit mixed in for like 5 minutes and super loud farts blasting out of control, after it was over i felt euphoric, I;ve never had this happen it was just like the scene in dumb and dumber when he takes a shit in the lady's toilet IIN? has this happened to anyone before? i wasnt sick or anything but earlier that day i ate some carrots that were in my car a couple days and had some mushy slime on them but like i said i didn't feel physically sick from it just my butthole hurted real bad
