This emoji shows a timidly sulky feeling, which is a bit different from being angry. It's more natural for expressing mild disappointment or hurt feelings than serious rage.

Among teens and people in their 20s, it's used more often to playfully pretend to be sulking than to show serious dissatisfaction. For example, you could send it when a friend is slow to reply, joking, "Why no reply? 🙎‍♂️" It can also be a cute expression used to get someone's attention.
