大概他喜欢甜的而我却姓颜
[dà gài tā xĭ huān tián de ér wŏ què xìng yán]
Roughly translated to 'Maybe He Likes Sweet Things But My Surname Is Yan,' implying an opposite nature in personality between oneself and others. One may favor a lifestyle with much sugar intake; meanwhile, another one's last name being pronounced in Chinese 'Yan,' meaning serious or plain, reflects different attitudes in life.
