I think you mean disorganised. You seem to have got thick right though, you must hear it a lot.
A pedant writes. Unorganised and disorganised are two distinct words. If your wife is normally a very together person but, on this occasion, hasn't sorted out the passport, unorganised is right. If she's normally a complete idiot and can't organise the proverbial piss-up, then disorganised is correct.
