These aren’t acronyms, but we use them quite a lot around here
Onciverse/Onceivere: The OUAT universe, the entire conceptual world of the show and the mythology in it.
Canon: a highly contentious term. In general you can interchange it with “established as law or as truth.” It means that OUAT has said “this is true to our show, it will not be changed on the show.” Snowing is canon: Snow and Charming are True Love and that’s not going to suddenly change. Often times it is thrown around before it is shown on the show (shipping wars, for example). Until A and E and show actually show it to us, it’s not canon.
