大概是他喜欢闹而我姓安
[dà gài shì tā xĭ huān nào ér wŏ xìng ān]
'Maybe he loves commotion while I seek peace'. This line seems to describe a contrast between two personalities - perhaps indicating someone (a significant other) who craves excitement and activity, versus oneself who values quiet stability, with '安' ('An') also happening to be the Chinese surname of the person using this as a username.
