嘴硬的女生欠吻
[zuĭ yìng de nǚ shēng qiàn wĕn]
It literally means 'A stubborn-lipped girl is owed a kiss'. An interesting notion used by someone possibly feeling affection toward an argumentative or obstinate girl, expressing a playful or flirtatious thought that such a tough exterior needs to be matched with tenderness or softened by kisses. It should be noticed it’s important for such behavior not overpass personal boundary.
