A person raising one hand, used to say 'me!', volunteer for something, ask a question, or flag oneself in a group ('who wants pizza' 🙋). It's a simple, near-universal classroom/meeting gesture translated into emoji form. Trivia: this emoji is one of the more literal, low-drift emoji on this list — its meaning has stayed close to its original intent since Unicode 6.0 in 2010, unlike neighbors such as the tipping-hand emoji whose meaning was hijacked by internet culture.
