神偷奶霸
[shén tōu năi bà]
It's a playful and humorous name where '神偷' (Shentou) means 'master thief' and '奶霸' (naiba), in Internet slang, means a person who excels at something (like 'boss of milk'). So, it implies the person is excellent in an unusual or unique way. However, the phrase itself sounds quite absurd and funny for native Chinese speakers.
