Our current tag finger_to_mouth appears to be ambiguous, being used for a few gestures I would consider semantically distinct.
One gesture, which I'd propose moving to finger_to_lips is the vertical finger across the lips gesture used to shush someone or call for silence. Examples: post #264561, post #303784, post #520708 .
Another is more of a "pointing to oneself" / "chewing on finger" gesture used to look cute / coy. Examples: post #423140, post #522471, post #484307 .
There might also be a few images in there that fit into a third group, but the vast majority seem to be one of the two above. What do people think about separating these into finger_to_lips and finger_to_mouth as defined above?
