colder than a witch's kiss

[W Brewer]

Euphemism vs. pejoration. Alright, let's play devil's advocate with the
witch's tits. Which came first, the tits or the kiss? In witch hunts, were
witches ever specifically identified by a coldness of bosom or by frigid
osculation?
The opposite argument would have a witch giving cold kisses (lack of
interest in male suitors? lesbian?). Then the vulgar-tongued would change
the expression to teats (bestial connotation) and tits (prurient).
