"banal or excessive sentimentalism," 1935, from Yiddish shmalts, literally "melted fat," from Middle High German smalz, from Old High German smalz "animal fat," related to smelzan "to melt" (see smelt, v.). Modern German Schmalz "fat, grease" has the same figurative meaning. First mentioned in English as "a derogatory term used to describe straight jazz" ["Vanity Fair," Nov. 1935].
