A obsessive compulsion to constantly flip upside-down shampoo bottles, to ensure they are right side-up. This causes confusion when the user realizes that the bottle was in fact designed to look upside-down, even though it is right side-up. Bringing the individual to think twice their every move, and increasing their level of Obsessive Compulsive Disorder.
