A word describing the act of giving (or getting) caressed in a loving manner. Derived from the Hebrew word for "pleasantness", it's commonly used when asking to be caressed, like a child would ask a parent or a person would ask his or her lover.
Honey, please give me Naim on my back?
Son, would you like some Naim?
