她喜欢走而我姓刘
[tā xĭ huān zŏu ér wŏ xìng liú]
A literal interpretation leads to 'She likes to go, while I have Liu for my surname'. This name might represent an individual whose romantic interest enjoys leaving him/her (perhaps physically or metaphorically), yet their surname happens to be Liu, which is a Chinese family name. There may be humor in this naming, as it creates a sentence with its two unrelated parts, expressing the helplessness or self-mockery of parting ways.
