你对他笑还跟他闹你牵她手还跟她抱
[nĭ duì tā xiào hái gēn tā nào nĭ qiān tā shŏu hái gēn tā bào]
Describing actions in multiple romantic relationships, the phrase translates into something like: 'You smile and play around with him; you hold her hand and hug her.' This can indicate polyamorous tendencies or just complicated love affairs.
