That's where the term comes from originally. The song Stan. Then in the mid '00s and '10s the K-Pop fans got so aggressive they started referring to them as "armies" and "Stans."
A "Stan" is a super fan that is so obsessed that they'll do irrational things if they feel that they or their obsession is being threatened.
