我嘴贱不讨你囍
[wŏ zuĭ jiàn bù tăo nĭ xĭ]
'Wo Jui Jian Bu Dao Ni Xi' literally translates to saying something impolitely does not win your happiness/pleasure, which may reflect a user with a self-depreciating sense of humor or playfulness that acknowledges speaking boldly or jokingly but aims at maintaining good relations despite any teasing mannerism they might have.
