Meaning
Eyes squeezed shut, eyebrows pinched upward and mouth open in a groan: a face that has had enough. It expresses exhaustion, frustration and overwhelm, often with a dramatic, whiny flavor.
It is perfect for venting about everyday struggles: “Still three chapters to read and it’s already midnight 😩” Some people also use it for intense longing, like craving a dish or admiring someone, which can surprise readers who only know the tired meaning. In a work chat, frequent use may make you sound more stressed than you are.
