how
because his brother is his biggest supporter and out of love he put his brothers name (zmjj) in the name.
ppl in asia actually have love for their family members
it's passive aggressive (very good imo, I approve)
Essentially, it's implying that he doesn't love his own family members
It's an acronym.... ZM is short for Zero Majors. KK is short for 'Korean King', as he is the best Korean player, even better than Lakia. Now that he won a major he'll probably change it.
