I had that exact thing happen to me at work. I occasionally have IBS-like symptoms a hour or so after eating where a sudden urge comes on with no warning. Almost always, I can just wait a few seconds and the pressure will subside with a rumble in my guts. Occasionally, it doesn’t subside much, but is never so bad I really worried I’d not make it to a bathroom and have an accident. This day I had a couple of glasses of iced tea at lunch, and I was bursting to pee by the end of an afternoon Zoom meeting. When the call ended, I hurried to the bathroom and, just as I entered, I felt the #2 urgency hit. Both stalls were occupied, and I realized holding back the bowel pressure made the pee urgency increase to the point of desperation. I rushed to the urinal just in time to avoid wetting my pants. Now I was trapped at the urinal, the pressure at the other end was growing rapidly, and I couldn’t stop peeing to try and hold it back. I tried to clench my butt muscles as best I could, but before I finished peeing, I lost control and began to slowly poop in my pants. I couldn’t tell how bad the damage was and couldn’t go into a stall to check, but could feel it was more than just a stain in my undies. I really didn’t want to run into any coworkers in that state, so I went straight to my car to drive the 15 minutes home and clean up. I put a grocery bag and towel on the seat, and started the 15 minute drive home. Of course, I never had the chance to finish the job because the stalls in the bathroom were occupied, so halfway home, the urge came back with a vengeance. I tried to hold on, but my bowels eventually gave up and I filled my pants while waiting at a traffic light.
