I'm in study hall minding my own business when I feel a breeze, I ask the guy behind me if he feels chilly and he responds "no". I continue with my own business when I start to feel something hitting me, as if someone is throwing something at me. I ask the guy again if he saw something be thrown at me, he once again responds with a "no". I pack my things and head home once study hall is over, I sit on the floor of my room and look back in my mirror and see that my buttcrack had been exposed all day long! I'm mortified! I was oblivious all day that my pants were sagging. Everyone is going to call me the buttcrack girl !
