Warning for certain words mod

[phsycical]

I'd like a modification that warns people when they're about to post a potentially inappropriate word.

Instead of submitting their post, after they click "Post reply" or "submit new thread", a page comes up saying why the word is generally unacceptable, and asks them to confirm if they really want to post it.

Most of these come from words that I generally find unacceptable (gay, retard, stfu, penis, porn), but don't want to completely censor since the words have some legitimate use. I'm aware I can manually moderate messages that are inappropriate, or post it in a document with the rules, but I feel this would be an easier and more targeted way to raise awareness about the rules, as well as eliminating any excuses like "I didn't read that part of the rules".
