Was she aware, I wonder Joe, that 'pill' in that sense means 'testicle'!? Following your clicky, I find that Wiki gives 'wazzock' as another 'mild expletive' for a foolish person; which is a good one. But I still wait to see if anyone can come up with one more altogether absurd in every way than "big girl's blouse". Anyone any idea of its origin, btw? I have simultaneously asked Michael Quinion, but of course don't know if he will feel able to reply.
