At the bus stop, my friend and I were sitting back to back. He farted so hard it went straight up my butt. It was the worst.
During lunch, two kids were sitting back to back. One of them let out a fart so strong it blew the other kid’s lunch out of their mouth.
At the movie theater, I was sitting back to back with my brother. He farted so loud it scared the person in front of us.
