Handshake emoji is the picture of the two hands, belonging to different people, who perform the gesture of handshaking. This emoji is used right in the same meanings the gesture is used in real life (probably, except for Handshake as “hello” to an important person like teacher or business partner, as emojis in conversations like that are not common) – i.e. as a symbol of a deal, greeting, or agreement on something. For example, together with 🗣️ Speaking Head emoji it may symbolize that the user has discussed and signed a contract.
Examples of using
“I closed an important deal today 🤝”
“I’m happy to greet you 🤝”
