站上冰箱当高冷
[zhàn shàng bīng xiāng dāng gāo lĕng]
This username implies the person is trying to act 'cool and aloof' by standing on a refrigerator, which may symbolize being above or out of reach in an amusingly exaggerated way. The humor comes from the contrast between the pose of indifference and the silly action of standing on a fridge.
