作业被我养的白白胖胖
[zuò yè bèi wŏ yăng de bái bái pàng pàng]
This nickname is a humorous and creative way of saying that the homework has 'grown fat' due to neglect or delay. It expresses the feeling of letting tasks (especially homework) linger unfinished, leading to a sense of guilt or humor towards one's procrastination.
