*Literally a stranger's mistake. I adapted it from Fremdfehler, which is an extraneous error. Example being a project of yours failing because of someone else's dodgy parts. There's also Fremdverschulden, which is the same idea but for accidents. Rear-ending someone because you yourself were rear-ended, for instance. Speaking of, isn't it funny that the word for debt (Schulden) is the plural of guilt (Schuld)?
