🤷 is a person with palms up and shoulders raised: a shrug. It comes as a neutral person, a man and a woman (🤷♂️ 🤷♀️), each in five skin tones.
It means 'I don't know', 'whatever', or 'it is what it is'. Depending on the question it answers, it can be honestly clueless, relaxed and easygoing, or a little dismissive. It's the emoji version of the old ¯\_(ツ)_/¯.
