My pants ruin story:
I was in the lunchroom in 9th grade, and I was going through an 80s phase, so I was wearing white jeans. They bet me I couldn't do 100 sit ups, so I said "Right now, bitch!" and I got down and had somebody hold my feet. I had just eaten so on every sit up I farted right in the guy's face who was holding my feet. Everbody was laughing, but he kept holding them and I just kept going. 100! I won, but apparent;y I had also been shitting in my pants. This was why the guy didn't move when I was farting on him, he wanted me to humiliate myself.
Big shit stain in my white jeans. Hundreds of people around. I took my shirt off and wrapped it around my waist. Like I said, I was in an 80s phase, so that worked. I walked out and went the fuck home. Got detention for skipping class, but was it worth it? Hell yeah.
