The tag alias #56255 supine -> on_back has been approved.

Reason: Prone is aliased to on_front, so it seems reasonable to alias supine to on_back.

EDIT: The tag alias supine -> on_back (forum #325457) has been approved by @slyroon.

I'd like to clean this up before the alias goes through. Mistag examples: post #1729109 post #2678384 post #2585930

Huh, I read that word and my mind jumped to porcine. Probably not a very common issue at all though.

I've never heard of the word supine in the first place. My dictionary lists two definitions for it:

1. Lying face upward
2. Passive as a result of indolence or indifference

If anything's being tagged after that second definition, that has nothing to do with being on a person's back.
Most of the images do seem to follow the first definition, with just a couple that seem to follow both,

but there are a few that don't seem to strongly fit beyond Matrix's list. Without anything to lay atop, how do we know they're laying and not standing or floating?
How do we know they aren't simply sitting?
And that last one is on_side not on_back.

If we can't tell if they're lying down, then they shouldn't be tagged on_back in the first place. Likely, the uploaders knew the artists' intention for the picture, but didn't look at it objectively enough to see that the intention didn't come through as well as expected. And that on_side is clearly a mistag.

Ok, I've gone through and untagged the posts that were mistagged and where it isn't clear that a character is actually lying on their back.

Anatomically, supine is pretty well established as the counterpart to prone. Considering that the second definition is more or less a metaphor and near-impossible to identify without more context, I would argue those sorts of posts would be better tagged with emotionless/expressionless (or, where applicable, distracted_sex).
