Rippling is a family of meta-level heuristics for controlling term rewriting in automated theorem proving systems. Special annotations are employed to control term rewriting. The family was developed (and continues to be developed) in the Mathematical Reasoning Group at the University of Edinburgh.

the appearance of waves or wrinkles in the breast due to improper fill of the implant, too thin of skin and not enough tissue coverage. This can happen with overs and unders - although with unders it is usually not visible on the upper portion of the breast.

Ridges from the implant that can be felt or seen around the edge of the breast. Some rippling is normal in saline implants. The below picture is a more sever case of rippling.
