A particularly strong form of nepotism, where not only are
family members given preference in hiring and promotion, but often in the face of incompetence,
poor work ethic, or
literally sleeping on the job.
The owner wouldn't fire his
son even after learning that whenever he's out of town, his
son will use his
father's office to take naps while everyone else continues to do their jobs. If that's not napotism, I don't know what is!
