I don't know much about the tags or rules in Meta, since I usually just briefly lurk, so I'd appreciate it if someone can fix the tags to be more appropriate and I apologize if I've broken any rules here.
I want to ask what reality-check really supposed to mean? recently I thought reality check more meant such a given concept is possible or plausible or working, but not necessarily mean checking reality or can be real, am I misunderstanding the meaning of this tag? My English is not that good so I may have misunderstood the obvious meaning here.
Is there any better tag for asking whether a concept is possible or plausible?
In the past I kind of hesitated to use this tag because I think science-based can cover it already, but after some of my questions get demands to have reality-check even though I have put science-based, I start to put it into one of my question but one of the deleted comment and answerer seems to assume I was asking about real bird counterpart or example which is not necessary nor it must be a bird in the context of my question and I don't know should I change the tag or not which probably ruin the answer which is frowned upon here.
In the past, I thought it was mean about literally checking reality or can be real, but after my past encounter and some lurking around other questions sometimes people demand reality check for the question even though the description or the context seems out of reality or fiction stuff but still in science base realm.
