I heard it's a funny term about dicks
Its a slang. 永康 . My chinese is weak but iirc jiji = cock .Touch my di*k Kang-Kang (zmjjkk) .
Edit : He Confirmed that not what his name means https://twitter.com/zmjjkk/status/1556581994146197504
If you are wondering where this meaning came from in the first place , it has been around for a while now since HK/TW challenger matches . So a lot of people thought that was the meaning of his name up until now.
Zmjj is my elder brother's game ID. his name is Ming jia Zheng
Then my name is Yong kang Zheng My game id is KK
Because my brother has unlimited support for me, I want to let the world see his ID So it becomes the zmjjkk you see
