我冷眼看着他和她
[wŏ lĕng yăn kàn zhe tā hé tā]
'Wo lanye kanzhuo ta he ta,' roughly meaning 'I am cold-eyed looking at her and him.' Choosing such a nickname may convey detachment, dispassionately observing actions between others (likely referring to former love interests), or even bitterness over lost possibilities while watching them move forward together.
