<human>: Could you distill the essence of the text into 1-3 sentences?

This was about 15 years ago between my Freshman and Sophmore years of high school.  Every 4 years our school band took a long bus ride to Florida to dress up in our snazzy outfits and march around the theme parks.  I don't know what I had eaten that didn't agree with me along the way, but it decided to show itself in the middle of the night as the bus crept along the road.  I was sleeping soundly when all of a sudden my gut was sending that signal that pooping in my pants was imminent.  I also know that one of the main rules of riding in a packed charter bus is to never use the toilet for number 2.  This wasn't going to wait so I shuffled along to the back of the bus where all the older kids were sitting.  I went into the bathroom and as quietly as possible I took care of business.  I knew that the cardboard thin door didn't conceal what I had just done and anyone sleeping just outside of it was now awake.  What I had hoped was that it didn't stir any of my attractive classmates awake(it did) and that the smell wouldn't linger.  I opened the door and dealt with a few stares and went back to my seat thinking that the worst was behind me(it wasn't).  Apparently the toilet wasn't functioning properly and it couldn't vent so for the next 3-4 hours, everyone had to smell what I unleashed in that bus toilet.
<bot>: Pooped in a crowded bus toilet during high school band trip.  The smell.  Oh god, the smell.
