look up any word, like oprah dollars:
 
1.
Korean Social Security Number.

Without this you will not be able to play that Korean MMO everyone's been talking about on the forums because Korea keeps every video game related account synchronized with a korean citizen ssn. Some people might think koreans are selfish but I think this is a very good measure against online pedophilia, trolling, fake bot accounts, and much more.
my brah wanted to play this new mmo called "continent of the ninth" but unfortunately he got denied since he didnt have a kssn.
