Tag Idea: shiver_lines

I've brought this one up twice before -- forum #47127, forum #50247 -- but I think I finally have a name for it.

How about shiver lines for that thing that happens, as in post #16738, when a the lines that compose a character's outer edges go zig-zagged to indicate surprise, sudden cold, or disgust?

Alternate suggestions: jagged shiver, shiver jags, shudder lines.

What about trembling and shaking tags?

Well, two problems with that.

First, trembling and shaking are actions, and I'm talking about tagging a specific visual indicator. For example, this is distinct from the tremble lines outside the character in post #1075628.

Second, shiver lines indicate a specific emotional response that those tags (and surprise) don't always convey. They usually convey:

A. The physical, shivering sensation from something cold, surprising, or unpleasant.
B. Dynamic shock that seizes the body. (Sometimes literal, electric shock.)

I'd say go ahead and use it. The distinction (disconnected motion lines vs actual warping of the character's outline) seems legitimate enough.
