When a person overuses something that belongs to another, believing it to be okay because of a self-appointed/designated right.

"Chiefin" references the foregone actions of Native American tribal leaders (chiefs) that had complete access to all of the tribe's resources.

In today's society, "chiefin" is commonly used to refer to those hogging the marijuana; although it can be said under a wide variety of circumstances.
