The closest "explanation" of the term "loess" I can find is in "Local regression models" by Cleveland, W. S.; Grosse, E. & Shyu, W. M. (Chapter 8 of Statistical models in S (1992) by Chambers, J. M. & Hastie, T. J.)
... local regression models is called "loess," which is short for "local regression," and was chosen as the name since a loess is a deposit of fine clay or silt ..., and is a surface of sorts. (p. 314).
