完了我生不了儿子怎么办没事我去生个女儿送给你
[wán le wŏ shēng bù le ér zi zĕn me bàn méi shì wŏ qù shēng gè nǚ ér sòng jĭ nĭ]
Meaning 'If I can't give birth to a son for you, then how about a daughter?', this nickname portrays someone humorous. Also, it implies traditional preferences for having sons over daughters, which are not always followed nowadays. It could suggest irony towards those outdated values or just a playful intention from the user.
