我姓裝叫裝純純
[wŏ xìng zhuāng jiào zhuāng chún chún]
'我姓裝叫裝純純' could be translated as 'My last name is 裝 (Zhuāng) and my name is Zhuang Chunchun (純純 means pure/purity).' Using one's name as a username suggests someone who embraces their own identity. The repetition of 裝 (a homophone) is likely done to make a unique and memorable online alias.
