On a backpacking trip, the better part of a day away from the trailhead. It came on so quick I didn't have time to run behind a tree, just dropped pants and let it out in full view of my travel buddies. As embarrassing as it was, it was the right choice. I didn't have any other pants to change in to and the distance we had to hike out would have led to far more serious health issues had I hiked in dirty pants.

I'm not sure what caused it. I was the only one who got sick. Probably a simple hygiene slip at some point. Someone didn't clear their hands well enough before cooking, or something made it past the water filters. I'm just glad someone had immodium and everyone gave me their spare fluids and electrolytes. I can see how a person could get really dehydrated really quickly and wind up in trouble.
