你站在冰箱边干嘛我想要变得高冷啊
[nĭ zhàn zài bīng xiāng biān gān ma wŏ xiăng yào biàn dé gāo lĕng a]
In this rather playful sentence 'Why are you standing next to the fridge; I want to appear aloof.' The nickname suggests a lighthearted comment on desiring a more distant, cooler demeanor even though they might actually have a friendly character.
