Yes, I was sitting on the floor in like 4th grade and then it just slipped out and everyone heard
It was so loud and it didn't help that the classroom was super small and we were like 8 people with the teacher. I couldn't help but laugh too, it was a mess
In 6th grade my friend and i were laughing in the middle of class and it just came out of nowhere. I couldn't hold it in and the whole class just turned around and stared at me. On top of that my friend slide his chair back so fast as if i just told him i had the ebola virus. It was so embarrassing.
