What’s your trad?

I was sitting in the Formosa Tea House just a minute ago, and a group of young people came and sat at the table behind me. Unable to keep from eavesdropping, I heard one say to the other “what’s your trad?” The answer appeared to suggest that all three were practioners of and/or adherents to some sort of wican system, and the “trad” was a reference to which branch, or “tradition” thereof. After this small learning opportunity, their conversation descended into small talk about who should get fixed up with who. Apparently everyone has a code name in this group. Fascinating.
