Correct technical term for this limestone solution weathering formation?

You are right about "clints" and "grikes" being the wrong terminology. "Grikes" or "grykes" are deep fissures that develop by the dissolution of limestone along joints within natural limestone pavements. "Clints" are the slabs of limestone that lie between and are isolated from each other by grikes. These features are associated with limestone pavements like those illustrated at http://www.limestone-pavements.org.uk/introduction... .

The feature that is illustrated by the picture on your flicker page is a weakly developed example of small-scale weathering features classified as "weathering grooves/rills" by Bourke and Viles (2007) and "rillenkarren" (ridges) and "rinnenkarren" (grooves) by other Earth scientists, i.e. Dunkerley (1979). In general, such features are collectively known as "karren".

I've heard this type of weathering most commonly called "tear-pants weathering" because it looks like it would tear your pants if you slide down the rock on your bottom.

This type of weathering could also be referred to as "differential weathering" since the ridges are more resistant to weathering than the rest of the rock.
