<human>: TIFU in the most embarrassing way.

Picture the scene: hot summer evening in UK heat wave. Due to a miscalculation I ate the wrong food for breakfast and had a bad stomach all day, but was rushing around London with little chance to use the bathroom. I needed to catch the next train leaving the city, but I chose rush hour, my second mistake. The hot sweaty train was packed and there were no seats and barely any standing room. Was like a scene from a news report about refugees escaping a war zone.

I managed to find a small niche in the only place, outside the toilet, and stood with the other passengers like sardines in a tin. Shortly after the train started moving, my stomach started to rumble hard and I thought years of sphincter training would protect me from having to use public restroom. Worst case scenario I could use the toilet. About an hour later I needed to go and relent, accepting defeat and head to the toilet..turns out, like most trains, it was out of order. I was going to have to hold.

In the heat of the day I was exhausted and decided to sit/squat. Like the final stand at the Alamo, I resisted until I couldn't any longer and my bottom winked open a loud whoope cushion fart, with accompanying rotten egg smell. The twelve or so people crammed in the tiny vestibule weren't impressed. I was exposed, and had to withstand shocked glances and dirty looks for another half hour. I couldn't say anything or look anyone in the eye. The only plus side was I didn't follow through.

Can you give me a shortened version of the text?
<bot>: farted on a packed train in a summer heatwave in front of multiple people, then had to stay with them till the end of my journey.
