Meaning
A round yellow face with lips pushed forward into a small pucker and plain, open eyes. It literally shows someone blowing or about to give a kiss.
Because the eyes stay neutral, it often reads as casual or cheeky rather than romantic, and many people use it as a whistling face when acting innocent. Add 🎶 for the whistle effect or ❤️ when it really is a kiss. For example: “Who ate the last cookie? Not me 😗🎶”.
