It doesn't currently, and it adds nothing to the question. Most of the time it's "urgent" because homework is due soon. Agree or disagree?
I agree. Right now there is a smallish list of words that will cause a warning to pop up when they appear in short question titles . From Shog9's answer the regex is
(Essentially a title containing at least one of the listed words and at most 30 characters before and at most 30 characters after matches the regex.)
urgent to this list shouldn't be much of a problem.
This word doesn't actually appear in too many titles (using moderator abilities, only 61 questions on the site, deleted and undeleted, currently have this word in the title). However it is often a sign of a terrible question: only 10 of these questions remain on the site undeleted. Of course, this word is often edited out by other users, but according to the SEDE, there are only 31 extant questions which were originally posted with "urgent" in the title.
