I think that we should limit expletives on our site, or at least with titles. I think that a few inappropriate words tucked away might be appropriate at times. However, in this question, it is used in the title. I think this looks somewhat un-professional, personally. Perhaps in titles We should use asterisks to accomplish this.
Also according to this page, expletives are not allowed anyway.
Some – like my English professor in college who also happened to raise dogs – might argue that bitches is not really an expletive in and of itself (even though it does have an offensive usage).
The easiest way to fix the question you link to, though, would be to simply replace the letter b with the letter p:
Pronunciation of “peaches” and “pitches”
(I assume that would be asking the same question, essentially.)
All that said, if I were writing a question, I’d avoid using expletives or patently offensive words in the title. That just seems like a common sense courtesy.
