ππ»ββοΈ: man raising hand: light skin tone, usually shown as a light-skinned man raising one hand straight up.
This usually means volunteering, asking a question, or saying 'I am in'. It is common in chats for participation and attendance.
For example, people use it for 'I can help!' or 'I have a question'. It also works well in group plans like 'Count me in ππ»ββοΈ for the trip!'
