Use of phrases directly from your rituals, signatures, etc.

I've had a similar experience, StealthMode, only it was online. Back in the days before I was on GreekChat, I was participating in another online Greek group. One day, I read a post in which the poster had used a sentence from our ritual. No quotation marks or anything, and I doubt anyone other than me noticed, and that post is what clued me in that he was a Sinfonian.

While I know it was used such that no one would have had a clue unless he or I clued them in, and while KDCat is right about the real meaning coming from relationships and shared experiences and values, I still was a bit uncomfortable with just planting a sentence from our ritual in an online post.
