Violation of entropy?

Ok so entropy cannot be destroyed, right? So let's say you have a reaction that decreases entropy (s<0) but it also is exothermic (h<0) and that overpowers the entropy decrease so it is spontaneous (ie hts=g<0). If that happens, where does the entropy go?

If that is a closed system, then you have just described a net increase in entropy.
Possibly it is the imprecise use of words that is confusing you  or you are pulling my leg. Redo the description, and describe it more carefully.

"destroyed" is an odd term to use here: entropy is energy. It doesn't get destroyed, it gets counted. And I don't think it is possible for a negative entropy reaction to be exothermic. Do you have any examples?
