A semi-imaginary disgusting substance usually found in a sweaty or private part of the body. Or sometimes in an untidy part of the house.

The "e" in ninkenst is rather softly pronounced - like the "a" in elephants.
Daddy is looking down one of the crevices of the couch for one of his daughters pretend earrings that she just lost. Upon retrieval of a surprisingly old crust of bread, daddy and little girl shout "ninkenst!!'

and find it funny.
