Where does the term “sasaeng” come from?

Download Article

Sasaeng behavior has been going on since the 1990s when groups like H.O.T and g.o.d initially popularized K-pop, but the term wasn’t coined until afterward. Since the 2000s and 2010s (following the introduction of K-pop into the mainstream), the term has been used to refer to the obsessive stalker “fans.”

Sasaeng Fans’ Motivation

Download Article

1
Sasaeng fans want to be seen by their idols by any means necessary. Attending shows and large meet-ups won’t give sasaeng fans the one-on-one time they desire. So, they often resort to stalking their idols, digging into flight, travel, and personal information (like texts and DMs) so they can find any info they can use to get noticed.
- At larger events, sasaeng fans feel like the crowd drowns out their individual presence. Their solution is to show up in the artist’s life constantly hoping it will get them noticed (and unfortunately, they’re often right).
- Real-World Example: In 2012, one sasaeng fan slapped JYJ’s Yoochun in the face as he was on his way to the hair salon, saying he’d remember her because she slapped him.
- Real-World Example: In 2011, a sasaeng fan attempted to kidnap Taeyeon from Girls’ Generation in the middle of a performance, grabbing her arm and attempting to pull her off stage.

The K-pop idol system may contribute to the sasaeng dynamic. Jesslyn explains that for K-pop stars, fame is their goal, and they're trained to be idols. “You are molded to be something that is above everyone else, that everyone should follow. And everyone should pay to see you whether or not the song is good or genuine or from the heart. It doesn't matter—the people come to see you, not for the music, and not for the dancing or the music video, just to see you as a person.”^{[3]

- Jesslyn goes on to explain that K-pop idols are different than typical Hollywood stars, which creates more parasocial, or one-sided, relationships. “So there are a lot of things that we have to do as a K-pop idol to do fan service....We have to be more welcoming to everyone to reach a certain level of fame...We actually engage in some way to cultivate that parasocial relationship.”^{[4]

- For example, Jesslyn explains, “We do fan calls...where we talk to fans and do what the fans want us to do. [Fans will ask us things], like “Could you say ‘Marry me?’ And sometimes we do it, just to engage with our fans.”^{[5]

- “Hollywood pop stars don’t have to do fan service,” Jesslyn continues. “If they don’t like it, they can be rude. They have more autonomy.” So, the K-pop “environment [can] cultivate a scarier dynamic than other types of celebrities. That’s why the sasaengs are there,” she explains.^{[6]
