Meaning
This face puckers its lips like 😗 but its eyes are closed in happy curves, giving it a contented, relaxed look. Literally it is a kiss given with a smile.
It suits light affection between friends, family or partners, a goodnight kiss, or humming a cheerful tune to yourself. It feels warmer than 😗 yet less intense than 😘 with its heart. Typical use: “Night night, sleep well and see you tomorrow 😙”.
