is any sloppy mess, especially that sweet mixture given by nurses to gossips who call to see the baby during the first month. The word simply means something warm. (Latin, calidus; French, chaudeau, Italian, caldo.)
(Mrs.). A curtain lecturer. The term is derived from a series of papers by Douglas Jerrold, which were published in Punch. These papers represent Job Caudle as a patient sufferer of the curtain lectures of his nagging wife.
