他说三十二号会来娶我她说三十二号会嫁给我
[tā shuō sān shí èr hào huì lái qŭ wŏ tā shuō sān shí èr hào huì jià jĭ wŏ]
Meaning 'He said he will marry me on the 32nd and she says she will marry him on the 32nd.' As the day does not exist (months only have up to 31 days), this expresses romantic naivety or impossibility of such promise. It can also reflect wishful thinking in relationships.
