我爱你想你一口吞掉你
[wŏ ài nĭ xiăng nĭ yī kŏu tūn diào nĭ]
Means something along the lines of 'I Love You So Much I Want To Swallow You Whole'. This is an intense and whimsical way to express deep love and longing, implying the overwhelming nature of love - so strong one might feel they'd want to encompass the entire existence of their loved one to always keep them near.
