TIFU by not researching home cold brew coffee enough

I bought a Hamilton Beach cold brew pitcher a couple years ago and haven’t used it until a few days ago, when it was in the high 80s (F°) for a while and I wanted a cold coffee drink. I added a ton of some generic medium roast grounds in it and then promptly forgot about it in the fridge. Few days later, I get up, find it in the fridge, decide I want to bring some to work with me. Figure it’s cold from being in the fridge and I don’t need to add ice. Here’s the FU. I didn’t know that leaving the grounds in there for so long would basically make it a concentrated Potion of Shit Yourself. And I drank a good 24oz straight up with only a little cream in it. I get to work, nothing happens at first. Within 20 mins I can feel the beginnings of an awful bathroom experience in my gut. I basically have to sprint-waddle to the nearest bathroom before I lose it. Thankfully made it to the toilet in time: the ungodly amount and sounds of the stuff coming out of my butt would have traumatized a small child. I was in there for a good half hour waiting for the shitstorm (literally) to stop. TLDR; don’t forget to google proper cold brew coffee techniques instead of just winging it and almost crapping yourself at work
