The eyeball emoji 👀 on Snapchat screams "I'm watching" or "I see that." It’s common in chats teasing secrets or gossip, like 👀📱📍 when someone’s tracking a story or 👀💼📊 when you’re keeping tabs on work updates. Use it to hint at curiosity or alert a friend you’re tuned in, whether it’s a late-night text or a group chat where the tea’s brewing.
