劣頑
[liè wán]
'Inferior Stubbornness' or 'Naughty and Reckless'. In Chinese, this username can carry a playful and rebellious feeling. The person who uses it may have a naughty and mischievous side, but does not take things seriously, and just wants to show a unique personality. In some contexts, it can also imply self-deprecation, showing humility or modesty.
