An action with the hands that used to be used solely an expression of agreement or acceptance, but when used as an emoji on social media can now also mean "I'm pleased for you, but don't want to carry on the conversation" - a polite version of "whatever" - a way of saying 'whatever' but pretending that you liked what they said.
A:"did you see my photo of the grand canyon. What an amazing place! You should visit it sometime"
