冰箱顶上装高冷踩着棺材跳鬼步
[bīng xiāng dĭng shàng zhuāng gāo lĕng căi zhe guān cái tiào guĭ bù]
This whimsical phrase translates as 'Being haughty on top of the refrigerator and dancing ghost steps on the coffin.' This unique nickname mixes elements of cold indifference with dark humor, possibly conveying a playful and rebellious nature that defies norms but also carries connotations of mortality.
