我毒舌我叛逆我没你会装逼
[wŏ dú shé wŏ pàn nì wŏ méi nĭ huì zhuāng bī]
This nickname 'Wo Dushé Wo Pannì WOMEI Ni Huì Zhuāng Bī' suggests a person saying they are sharp-tongued (sarcastic), rebellious and without their special person, all that remains is trying to act cool (a slang term that could translate as posturing or putting on a show).
