lampbane The worst episode of Star Trek: The Next Generation. Sometimes things aren't just bad, they're Sub Rosa-bad. Oct 27, 2008
bilby "The similarity was eerie precise because there was on one thing the protesting, horrified eye could pin it on. It was sub rosa, deeply buried between the lines, but so real it shrieked: that trick of crossing the feet during the stretch, of splaying the fingers stiffly beside either thigh, the tight little crinkle of the eyes."

seanmeade Sub rosa comes from the Latin, literally "under the rose," from the ancient association of the rose with confidentiality, the origin of which traces to a famous story in which Cupid gave Harpocrates, the god of silence, a rose to bribe him not to betray the confidence of Venus. Hence the ceilings of Roman banquet-rooms were decorated with roses to remind guests that what was spoken 'sub vino' (under the influence of wine) was also sub rosa. Mar 26, 2007
