I get it a little, but I don't quite understand exactly what you mean.... or like what type of warning. (It's probably just me, not your portrayal of the concept. It's nice to excercise my mind with concepts like these sometimes.)
I think the artist is trying to convey a sense of dangerous attraction. Something along the lines of 'man eater' or 'heart breaker'.
The idea seems to be that the woman in question is incredibly attractive, but less than emotionally perfect so that she either creates an environment which is hostile to emotional attachment, or is simply incapable of it.
