What is a fly by night girl?
I'm curious, could you elaborate on the term "fly by night girl"? It seems to be a colloquial expression, but I'm unsure of its exact meaning. Is it a reference to a woman who is untrustworthy or unreliable? Or does it have a more nuanced meaning that I'm missing? I'd appreciate it if you could provide some context and clarify the term's usage.
