lutose (adj.)

"muddy, covered with clay," from Latin lutosus, from lutum "mud, dirt, mire, clay," from Proto-Italic *luto-, *lustro-, from PIE *l(h)u-to- "dirt," *l(h)u-(s)tro- "dirty place," from root *leu- "dirt; make dirty" (cognates: Greek lythron "gore, clotted blood," lyma "dirty water; moral filth, disgrace," lymax "rubbish, refuse," lyme "maltreatment, damage;" Latin lues "filth;" Old Irish loth "mud, dirt;" Welsh lludedic "muddy, slimy; Albanian lum "slime, mud;" Lithuanian liūtynas "loam pit").

Hence also English lute (n.) as a type of tenacious clay or cement used to stop holes, seal joints, etc. (c. 1400), from Old French lut or Medieval Latin lutum, from the Latin noun. Lute also was a verb in English.

rinky-dink (adj.)

"trivial, old-fashioned, worthless," 1913 (from 1912 as a noun, "antiquated or worthless object"), said to be carnival slang and imitative of the sound of banjo music at parades [Barnhart]; compare ricky-tick "old-fashioned jazz" (1938). But early records suggest otherwise unless there are two words. The earliest senses seem to be as a noun, "maltreatment," especially robbery:

So I felt and saw that I was robbed and I went to look after an officer. I found an officer on the corner of Twenty-fifth street and Sixth avenue. I said, "Officer, I have got the rinky-dink." He knew what it meant all right. He said, "Where? Down at that wench house?" I said, "I guess that is right." [testimony dated New York August 9, 1899, published 1900]

And this chorus from the "Yale Literary Magazine," Feb. 1896:

Rinky dinky, rinky dink,
Stand him up for another drink.
