傻子说我爱上了疯子
[shă zi shuō wŏ ài shàng le fēng zi]
'Fool in Love with a Crazy' indicates that both people in a relationship behave in irrational and whimsical ways, just like being called a fool in falling in love with crazy person who acts unpredictably. This nickname reflects a kind of self-mockery on one's passionate but imprudent affection, or the feeling of falling for someone unpredictable or unusual.
