Lacking any other action or expression, this emoji gives off a very objective and neutral feeling. This makes it useful for when you don't want to reveal your emotions or to express an awkward, speechless moment.

In a group chat with many people, when you have nothing particular to say or it's awkward to jump in, you can send just this emoji to convey, "I'm just watching." It can be used to humorously break an awkward silence or to wittily express your subtle position.
