Nothing worse than an unexpected fart.
One time when I was like a freshman in High School, I was this girl's house with friends, we were all watching movies or something. New Jack City, I think. Anyways there was 3 girl and 3 dudes, so kinda like a date. I was laying on the floor with the girl I was matched up with and she stood up to go to the bathroom or something, I was laying on my back, and she stepped on my stomach, jokingly. She put her all her weight on me, and it squeezed out a fart. It was loud and sounded like it had a lot of force behind it. Everyone heard it. The rest of the night I was refered to as "fart boy". Needless to say, I didn't get any from her.
