英英字典上说，Flirting 是 express 性，浪漫方面的调侃话。而我们有时说些俏皮话，英文可用playfull

or playfully.如果你在当时没听错的话，我觉得 flirting这个词的用法的解释托尼说说错了。所以我在你的上一篇就问托尼是不是英语教育的科班出身。大都在中国的所谓外教就是在外国失业后跑去的

Flirting is a form of social communication, often playful or subtle, used to express romantic or sexual interest in someone. It involves behaviors like smiling, direct eye contact, teasing, light physical touch, and compliments. 

"Would you take offense if I had the gall to plant a kiss on this beautiful shoulder?" "You'll figure that out soon enough after the deed." (poster by Henri Gerbault)
