Jarbex
When two people, walking toward each other, attempt to go around one another, but instead head in the same direction. They then stop and attempt to switch directions so as to avoid running into each other, but because they both have chosen to change direction at the same time, the exact same thing happens again. This can happen over and over again until one of them decides to stand still and just let the other person choose which way to walk around.
