The straight line mouth emoji is the universal sign for "I'm not impressed" or "This is awkward." Use 😑🚧 when something’s a total no-go, or 😶📏 to measure just how unimpressed you are. Drop 😐🛣️ for those long, boring conversations or 😑➡️ when you’re just pushing through the day. It’s the perfect reaction for deadpan moments in texts or when a meeting drags on forever.
