他是我的逗比她是我的白痴
[tā shì wŏ de dòu bĭ tā shì wŏ de bái chī]
A somewhat teasing term to describe someone close who can be very silly (him - being comical) and someone else (her) who can be seen as naive. It's often used between intimate relations like good friends or couples where they understand each other beyond such casual titles.
