current_user is a LocalProxy. Other examples are current_app, g, request,
and session. You can create your own, it's documented in Werkzeug:
http://werkzeug.pocoo.org/docs/0.11/local/#werkzeug.local.LocalProxy. How
you create it depends on what your data is, but in most cases you probably
want to pass a callable that returns the object.
