What's the dumbest way you accidentally started a school trend?

In 9th grade, I wore my dad's old construction vest to school because I lost a bet with my brother. Bright orange with reflective strips everywhere. It was absolutely massive on me, hanging past my knees like some weird neon dress. My brother laughed so hard he almost choked on his cereal when I came downstairs.
I walked into first period expecting to be roasted alive. My history teacher just stared at me for a solid ten seconds and said, "Bold fashion choice." Everyone laughed, but then this popular senior girl took a picture and posted it with "Safety Core is the new aesthetic" and tagged me. Within an hour it had like 200 likes.
By lunch, three kids had borrowed vests from the drama department. One guy wrapped yellow caution tape around his backpack and water bottle. Someone else wore a hard hat to math class and refused to take it off when the teacher asked. My friend started directing hallway traffic with a reflective wand he stole from his dad's emergency kit.
Next day, it was everywhere. Art kids painted elaborate designs on vests they bought from the hardware store. Theater kids wore them over fancy clothes claiming it was "industrial chic." Band kids added reflective tape to their instrument cases and drumsticks. The chess club showed up in matching yellow helmets. Even some teachers got in on it. One English teacher wore a tiny reflective pin that she insisted counted.
When I walked in Thursday, I almost had a heart attack. At least fifty students were wearing construction gear of some kind. The shop teacher was completely confused when kids started asking to borrow his safety goggles and work gloves. He thought there was some kind of inspection happening.
The principal called an emergency assembly that afternoon. "While I appreciate your sudden interest in workplace safety and visibility," she said with that fake smile adults use when they're annoyed, "this is becoming disruptive to the learning environment." That just made it worse. Kids started calling themselves "The Visibility Movement" and claimed they were protesting against being "unseen."
Friday, I opened my locker to find it completely FILLED with mini paper vests people had made from construction paper and aluminum foil. Someone had created an Instagram account called "VestLife" that already had over 400 followers. They posted daily "fits" of the best safety gear outfits. I was tagged in everything as the "Safety Pioneer." My brother thought this was the funniest thing that had ever happened and took videos of me getting recognized in the grocery store.
The local news showed up Monday morning. I walked into school and there was a camera crew interviewing kids about the trend. The reporter stuck a microphone in my face and asked why I started wearing safety equipment to school. I completely panicked and said I was "taking a stand for safety awareness in educational environments" instead of admitting I lost a bet about who could eat more pizza rolls at 2am.
Two weeks later, the school board announced they were creating an official "Safety Awareness Month" every year. Three construction companies donated actual safety equipment to our shop class. I got a certificate of community leadership that's now hanging in our school's trophy case right next to football championships.
All because I lost a stupid bet over pizza rolls. My brother still brings it up at every family dinner.
