我自恋我矫情我装逼我爱你我罩你我忍你我养你我爱你
[wŏ zì liàn wŏ jiăo qíng wŏ zhuāng bī wŏ ài nĭ wŏ zhào nĭ wŏ rĕn nĭ wŏ yăng nĭ wŏ ài nĭ]
This is a rather playful and exaggerated nickname that translates to 'I am narcissistic, I'm moody, I like to show off, I love you, I protect you, I tolerate you, I support you, I love you'. It suggests someone who is expressive and maybe a bit overly dramatic.
