What is "churchy?"

Tonight Dave (a Presbyterian missionary) and I talked about our faith together. We were able to joke about our individual callings. But then he said that he wants to talk about his faith with his friends at home. I froze up. I don't talk about my faith with my friends. I call this my fear of being "churchy." It's not that my friends do not have faith or wouldn't be supportive. Nor is it because I do not enjoy what I do. It's because sharing my faith leaves me vulnerable. If I admit that I like good sermons, good church music, talking about my calling even going to see old churches (I can't believe I am admitting to this.), then I am sharing what is most important to me, my faith. Is that "churchy?"
