What exactly does negative entropy represent?

I don't think you should worry too much about negative entropies. Usually entropy is measured as delta S, or the change in delta S. A negative delta S indicates that the possible microstates (amount of "disorder") has decreased from previously. The only time that molar entropy is negative (look at Appendix 2A) is when the substance in question is an aqueous ion.
