Portmanteau of "skin indentation".

When clothes are so [[tight clothes|tight]] they indent into the skin and make the surrounding flesh bulge outwards. For example, tight [[thighhighs]] that cause the thighs to bulge over the top.

See [[deep skin]] for when skindentation is caused by groping instead of clothing.
