saturday's smarm definition, paraphrased

Boy: Wait, wait, when does "flirting" turn into "smarming"?

Girl: When it becomes clear that the flirting male is doing so to get into your pants, not just to be charming. It is particularly smarmy when said male has a wife or partner and therefore has no business trying to get into your pants.

Boy: Okay, thanks. I wasn't clear on that

Girl: That's today's definition. Don't expect the same answer twice.
