贝比你是我的唯一北鼻你是我的一切
[bèi bĭ nĭ shì wŏ de wéi yī bĕi bí nĭ shì wŏ de yī qiè]
'Baby, you're my only baby, you're everything to me' emphasizes extreme adoration and possessiveness. In Chinese internet slang, people often replace similar-sounding characters to add cuteness, making this a very intimate and expressive nickname full of endearment and passion.
