@BarefeetChaser Those examples aren't even all the same pose, so I don't think there's a single generalized answer to your question. Compare post #55826 (standing straight up, hands at waist level) with post #2557172 (sitting, hunched over, hands up to the face). Then there's the arms spread, dual-wielding pose in post #1300221 which looks nothing at all like any of the rest.
If you want a tag for the gesture in post #55826 with palms up and hands apart, there are some examples of this being tagged open_hands -- post #3088064, post #3090157, post #3422368, etc. -- but the tag is undefined and used for a variety of poses, so it may require cleanup. Or maybe we need a new tag, like open_cupped_hands or something like that.
If that isn't what you were looking for, you may want to rephrase your question to be more specific, because I'm not exactly sure what you want at this point.
