What a body becomes once nobody's paying rent inside it anymore.

means The dead body of an animal, or (dismissively) a human body, or the leftover framework/remains of something once it's been stripped of use.

from From Old French 'carcois' or 'carcasse,' which came from a Vulgar Latin root tangled up with 'caro' (flesh — the same root that gives us 'carnal' and 'carnage'). The exact path is murky and etymologists argue over whether a Latin word for 'skeleton' or 'body' fed into it, but by Middle English it had landed as 'carcays,' meaning a dead body — usually an animal's. The spelling wobbled for centuries before settling into 'carcass,' and the word kept its grim, stripped-down sense of flesh and bone with nobody home.
