How it's used
Refers specifically to money that is unlikely to be recovered, often due to the debtor being untrustworthy or having financial trouble. It carries a strong sense of frustration and resignation, implying that the lender has essentially written off the loss. The term is frequently used in business contexts or when discussing personal loans between friends that have gone sour.

Do not confuse this with 壞賬, which is the formal accounting term used in professional or banking contexts. 爛數 is strictly colloquial and should be avoided in formal financial reports or legal documents.
