I said "she might be", and using the broadest possible terms, that is, that she is a female, and that a tart is a derogatory term for a female, and that therefore all females could potentially find themselves being referred to as a tart, in the same way that all men could be regarded as potential dickheads, and furthermore taking into account that the term "tart" ranges from mildly to deeply offensive depending upon context, culture, and the understanding of the person using the term, I stand by my initial statement whose primary function is, after all, the set-up for the punch-line of a joke which depends upon innocuous word-play and the discussion taking place in recent posts immediately above mine.
Yours, etc.
