The process of inserting the end of a finger, generally the index finger, into another person's navel and wriggling it about.
Wendy squealed as Bob Navel Raped her, giving a ticklish sensation to her belly with the wriggling finger.

A pleasurable experience that is akin to fluffing.
As he was Navel Raped, Bob felt all his naughty bits tingle with pleasure.
