I find it interesting that you chose not to mention your domain name in the title of your home page as well!
If i understand what you say correctly, it is an unique phrase that might not be found elsewhere on the web. Is it true?
Is the rank that you see now for the 2 words together without a space or with a space between the two words?
So the domain url was the only place where google found it and that IMO isn't enough for google to automatically give it some weight and rank your site. All it needed was a mention of that unpopular phrase somewhere in the html source code of the page.
