"loaded" or "fully loaded" or "self supported" are the same thing, as far as describing one type of bicycle touring, generally speaking. Splitting hairs is another form of entertainment all together.
As I see it. If all it takes for you to get by on a bicycle trip is a bottle of water, 2 granola bars, flask of whiskey, helmet and a pink tutu, you are loaded and/or self supported. If you feel you need to take all you can possibly carry plus dragging the kitchen sink behind, in order to get by, you are loaded and/or self supported.
That makes sense if we are all together on the term "get by".
Happy New Year, everybody!
