Meaning
A face with smiling eyes and one hand pressed over its mouth, as if stifling a giggle or catching itself after saying too much. Depending on context it means a suppressed laugh, playful shyness or a cheeky “oops.”
It is handy for gossip, teasing and little slips: “I may have told her about the surprise party already 🤭” It can also react to a compliment with modest delight. Some users read it as more mocking, a hidden snicker at someone, so be careful replying to a person who is sharing something embarrassing.
