But here is the thing... I don't think I have ever used it in a sentence, until now.

It is not easy to use the word breach in a sentence unless you are quoting from the Bible. It is in Proverbs 17, so check it out and find the verse.  

Breach.... 

I like it.  It rhymes with preach, and peach

               Also can be spelled breech, but that does not have  the same meaning.  

The English language....so interesting.
