A Zeroeth Law is a law that is added to another set of laws at a later date.
It is usually so important that the other laws cannot function without it, yet so obvious that nobody thought it needed stating.
The Zeroeth Law of thermodynamics: If objects B and C are both in thermal equilibrium with object A, then they are in thermal equilibrium with each other.
Isaac Asimov's Zeroth Law of Robotics: A robot may not harm humanity, or through inaction allow humanity to come to harm.
Newton's Zeroeth Law of Motion: If objects A and B are moving relative to object C at velocities v1 and v2, then they are moving relative to each other at velocity v3 which is the difference between v1 and v2. (Note: This law is now known not to be true, especially near the speed of light. That's where Einstein comes in)
The Zeroeth Commandment: Thou Shalt believe all of this and never question what thou art told.
Someone who jumps from one relationship immediately into another one.
Serial monogamists can not stand to be alone and often suffer from vast commitment and insecurity issues.
Because they jump into relationships immediately after the previous one has ended, serial monogamists typically don't take the time to reflect on their behavior or why their previous relationships failed; thus, they end up making the same relationship mistakes over and over again.
