That's clearly an arched_back within the realm of human anatomy.

A contortionist could probably pull that off.

There you go.

I feel like anatomy flagging is heading to the extreme. There are probably thousands of picture here that have people posing in a way that ordinary people can't and/or don't usually do or having weirdly sized body parts, sometimes it may even be a little bit more extreme than normal. But I feel like that's part of the fun of a picture compared to a photo. Things are emphasized for our enjoyment. Flagging (or even adding the bad anatomy flag) has become like: if I can't do it or if my body part isn't as small/big as theirs, then it's wrong. If this is the case, when aren't all pictures here flagged? Their eyes are HUGE compared to normal people. Certainly that's bad anatomy? I think we need to reassess the situation.

That's scary.

Women are usually more flexible than men, not that weird.
