When you have the worst diarrhea runs. The shit sometimes just drips out of your ass crack, and on the floor causing an embarrasing moment for everybody. These runs usually happen every ten to fifteen minutes or so and maybe not coincidentally occur after dinner. They are especially bad when a sports movie is playing. The problem has not been diagnosed scientifically yet but it is clearly an issue in modern america society.
