In my first week of college, hanging out in my (coed) dorm with my roommate and 5 or 6 of our dude neighbors, we had the brilliant idea that my roommate should pop my back the way that requires you to lay face down. There wasn’t enough room on our floor, so we went out into the hallway, and everyone decided to follow us and watch. So there was a sizable crowd around me in a public hallway while my roommate pressed down on my back, and I let out a nice loud fart. I laughed it off along with everyone else, but I’m sure my face was bright red. It was a wonderful first impression to make!
