look up any word, like spook:
The cleavage seen when a women is wearing a very high cut top. Basically, the tops of the breasts will be covered but from about an inch below the nipples and down will be bare. The word is a portmanteau of "cleavage" and "nether" (meaning under, or below).

This shirt has shrunk so much in the wash I'm practically showing off my nethage.
