What is the definition of Movement Mortgage?

A 'ovement mortgage' is a fancy term for when you buy a house because your friends are moving in, and you're not quite sure if that new place is still yours. It's like buying a home on the spot while waiting for your friends to move in, but with all the legal paperwork and potential for a moving truck blocking your front door.

Edgy example sentence: "Last week, my roommate and I signed a movement mortgage on this tiny studio apartment because we were just about to move into 'The Invisible Room' - and now I'm stuck in a place where I can't even see my own reflection, let alone my own mortgage balance."
