create alias bouncing_lines -> motion_lines

Utility alias. For discoverability along with related tags like bouncing_breasts, bouncing penis etc.
Example post #4806662

Would it better if the alias was bounce lines, or not? I'm not sure how this sounds to a native English speaker, but it sounds okayish to me.

What the hell are bounce lines?

I'm getting the strong impression that most of these "utility aliases" are for yourself and not because other people are having problems searching.

Some images do have lines to show a ball's path as they're bouncing. Not sure that's what the OP is referring to.

Example: post #2752499, post #4203058

I've never heard of "bouncing lines" as another word for motion lines. Googling bouncing lines, I just get the lines of a bouncing ball, as mentioned above. This isn't quite the same thing as motion lines.
