I imagine this is some sort of chemical approximation of mirror Kirk’s natural Kirk musk. I figure regular Kirk wore cologne. Hell, regular Kirk probably bathed in a special blend of alien pheromones and ground walrus penis. So, mirror Kirk probably didn’t wear cologne. He also probably didn’t bathe.
Maybe he was monogamous, too? Perhaps that’s what really disturbed regular Kirk about the mirror universe. That somewhere out there in all possible worlds there was a version of him not trying to get it on with every half-dressed alien female/female-equivalent-gender he saw out of the corner of his eye. It must have been terrible for him.
