Rick,
My 1972 Penguin "A Dictionary of Geology" gives the following:
"When one surface of a rock moves over another surface in close contact under pressure, the two surfaces develop a kind of polish, with linear grooves and ridges parallel to the direction of movement... ".
It goes on and mentions faults but that's the gist. So I don't really see much incompatibility between what you assumed and what the interweb says.
All the best,
Anthony

Airing my ignorance in public..... Could someone clarify exactly what a slickenside is - I'd assumed that the term referred to a polished fault surface, however a quick internet search muddied the waters, reference being made to the striations on the fault surface as slickensides.
