我腹黑我泼妇我没你会装
[wŏ fù hēi wŏ pō fù wŏ méi nĭ huì zhuāng]
Expresses confidence and perhaps a bit of arrogance, acknowledging the user's cunning nature and readiness to act aggressively ('fu hei' means having malicious intentions). Also teasing another person for not being able to hide emotions as well as they can.
