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

As usual this didn't happen today. Probably around September before I graduated college. First some background: I went to a small university that was built on a steep hill at the end of the town. I had an apartment in town and while the distance wasn't very far, the hill made the walk to campus horribly inconvenient. Being the genuinely good people they are, the university provided a bus service that picked you up downtown and dropped you off at the top of the hill. Since I'm hella lazy I usually took the bus and since I'm not too keen on talking to strangers in the morning I always wore headphones.
Now the FU: On this particular day I was mildly hungover and because of this had some, dare I say, intestinal discomfort. The bus stop wasn't very crowded, just me and a few girls who lived in the apartment building next to mine. I was standing and they were sitting on the bench when suddenly I felt it coming. It was just an awful pocket of flatulence brewing inside me. The wind was blowing and I was assuming it wouldn't be loud so I just let it go. I was delighted when it was quite silent even though I felt my cheeks flapping away. A gust of wind came to blow it away almost immediately. I thought nothing of it until I caught a glimpse of the girls behind me. One of them was laughing hysterically and the rest were staring at me looking completely mortified. I suddenly realized I was listening to music, and while I didn't hear the noise my bottom made, that didn't mean it didn't make one. I flushed red, hid my face, and clenched my butt for the rest of the day. I saw these girls quite constantly throughout the rest of the semester and couldn't once bare to make eye contact with them. On the bright side I graduated in December and never saw them again!
<bot>: I passed gas at a bus stop with headphones on and thought everything was ok because I couldn't hear it. I was dead wrong.
