A property-owner's-loan contract with terms that are so grievous and/or long-term that the only time you will likely ever be relieved of it is after you "shuffle off".
A clever early-'80's cartoon-example of a morgueage: a scowling bill collector is shown speaking to a "Here lies John Smith" gravestone: "And so I am warning you for the final time, Mr. Smith --- if we do not receive your payment within two weeks, we are gonna hafta take some STERN STEPS! Do you hear me, Mr. Smith?! STERN STEPS!"
