Thanks for pointing that out to me. I checked the VtM Core Book, then changed the Chapter 1 and Glossary prose to make them more consistent with the canon definition. That version is now live.
Oh, I actually just meant that the player should know what it means before they make the selection, not that it *has* to match canon. I just got blindsided by thinking I knew what it meant based on canon, and not realizing I actually had no information about what it meant in the context of the game. But it is clearer now anyway.
