The debt that keeps billing you after the party's long over.

means Money you owe that's overdue — payments you should have already made but haven't.

from From the Old French arere, 'behind, backward' (built from the Latin ad retro — literally 'to the rear'). The same retro root that gives us things lagging or looking backward shows up here as debt that's fallen behind schedule — you're not broke, you're just stuck in the back of the line you were supposed to have already cleared.

origin
from old french for behind, literally
common use
rent or child support unpaid on schedule
sneaky meaning
paid in arrears just means paid after service
not always bad
some salaries are legally paid in arrears
