It's hard to classify some human actions and activities, but despite not having a particular category, they are still very important. That's why there is an emoji for a person climbing the cliff, for example. Or a person standing still. Today they (or I assume it's a male) relaxed in the sauna, then got a haircut and a head massage. Overwhelmed with happiness, he rose from the knees, levitated, but got tired quickly. Now he is not walking, not running, not dancing, but just standing on the ground. Because he can. Taking this into account, I conclude that this emoji is pretty exciting, although it seemed useless at first.
