debunkering (verb)
Nautical term:  To offload unusable and/or volatile fuel or waste from a ship.  As opposed to bunkering, which means to load fuel into a ship's bunkers (containers for storing a ship's operating fuel). (RM)
Note:  By definition debunkering is to offload onto something else.  Otherwise, it could simply be jettisoned.  I include this term here because, as with the nautical term yar, it could be applied to a person.  For instance, one could debunker a volatile or useless spouse onto her lover.  You can also jettison a spouse; debunkering implies a landing platform or place to go, an arranged exit.  I first heard this use in the Netflix series Maestro in Blue (season two, episode five).
I once encountered a clever department manager who launched a debunkering operation for a useless employee in order to move said employee to another, unsuspecting department.  Of course, the new department would eventually learn of the problem and they would have to either endure the useless employee or go through the hassle of terminating her.

dhimmitude (noun)
Word coined by historian Bat Ye’or to describe the status of dhimmi peoples.  In Islam, after jihad concludes in a given area with the conquest of infidel territory, a dhimma, or treaty of protection, may be granted to the conquered People of the Book, historically, Jews, Christians, and Zoroastrians.  The dhimma provides that the life and property of the infidel are exempted from jihad for as long as the Muslim rulers permit, which has generally meant for as long as the subject non-Muslims, the dhimmi, prove economically useful to the Islamic state.  The Quran spells out the payment of the jizya (poll or head tax prescribed in Sura 9:29), which is the most conspicuous means by which the Muslim overlords exploit the dhimmi.  But the jizya is not merely economic in its function; it exists also to humiliate the dhimmi and impress on him the superiority of Islam.
