*feels a bit clever for once*

I've heard of this one!

lily-livered - Weak or lacking in courage; cowardly; pusillanimous.

But surely, for your own sake, you will not be so lily-livered as to fall into this trap which he has baited for you and let him take the very bread out of your mouth without a struggle.
-- Anthony Trollope, Barchester TowersHe had skin as white as a lily, but he was not lily-livered; he was as strong as a champion at the Shrovetide games.
-- Geoffrey Chaucer and Peter Ackroyd, Canterbury Tales a pretty well known expression I expect..and like many, was first coined by Shakespeare..

The liver was supposedly the seat of passion and was typically dark red or brown. Since a lily is pale and light-colored, a lily-livered person was weak and passionless.

hmm... don't know why he had to pick on lillies.. I think they're rather nice myself.. but, whatever.

anyway, Happy November.
