sasaeng

In Asian and specifically South Korean culture, a sasaeng, or sasaeng fan (Korean: 사생팬; Hanja: 私生팬), is an obsessive fan who stalks, or engages in other behaviour constituting an invasion of the privacy of a Korean idol or other public figure.

As BTS was leaving the airpot to get to their flight, a sasaeng came and tried to tackle one of the members.

STARMY

Stay + ARMY. It is the Stray Kids fan base and BTS together. It is used mostly when the two is your favorite groups, but you cannot use only one.

I became a STARMY instead of a Stay or an ARMY.
