Meaning
A face with one eyebrow arched high and a flat mouth, the look of someone not quite buying what they just heard.
It signals doubt, mild suspicion or “excuse me?” when a claim sounds fishy. It is also used for comic disapproval among friends. Pair with 🧐 for detective vibes or 👀 when suspicious. A typical reply: “You finished the whole project in one night? 🤨”.
