With the increasing fame of K-pop artists worldwide, anything they do can easily become a hot topic. Their huge influence on fans is evident whenever they start a trend, whether consciously or unconsciously.
Fans participate in these trends as a way of bringing themselves closer to their idols and engaging with other members of their fandom. In some cases, such trends even reach non-fans as well!
Here are some fan trends and challenges popularized by K-pop idols that became viral:
Finger Heart

When non-fans think of K-pop or K-dramas, one of the first things that come to mind is the finger heart pose. Typically used by Korean celebrities as a gesture of sending their love to fans, the finger heart pose is made by crossing the thumb and index finger to form a small âheart.â
Although it remains uncertain who invented the pose, its popularization is linked to certain K-pop idols like Big Bangâs G-Dragon and INFINITEâs Nam Woohyun. The finger heart is just one of the ways that K-pop idols express their love for fans. Likewise, fans participate in this trend and often make this pose to signify their connection with Korean culture.
Dance Challenge Collabs

Until recent years, you wouldnât have imagined K-pop idols promoting their songs on TikTok, much less collaborating with other artists for a dance challenge. Thanks to Zico and his âAny Songâ challenge with MAMAMOOâs Hwasa in 2020, dance challenge collabs have now become a must for K-pop idols during their comebacks. More often than not, these challenges consist of basic steps that fans can pull off. For idols, itâs a good way to make their songs go viral as more people participate in their dance challenge.
Fans love seeing their idols mingle with other artists, especially if itâs with celebrity friends or those whoâve never publicly interacted before. Itâs also a way to see their idols do a cover of another artistâs song, albeit briefly. Because of TikTokâs algorithm, there are cases where a dance challenge made by someone other than the artist becomes popular (like EXOâs âFirst Snowâ) or an old song suddenly goes viral years after it was released (like TWICEâs âLook At Meâ). Fans also participate in dance challenges with their friends, sometimes even adding their own touch to the steps.
Gwiyomi Song
If youâve been active on social media since 2013, youâve probably encountered this Internet craze before. Featuring a catchy melody accompanied by a series of cute hand gestures that match the lyrics, the Gwiyomi Song trend was popularized by Ilhoon from BTOB. It shows increasing levels of cuteness, with each set of gestures counting from one to six. Fans and idols alike participated in the trend, some even creating playful interpretations of the song!
Random Play Dance

Your K-pop fan experience wouldnât be complete without witnessing a random play dance in public. The Random Play Dance started as a game for guests appearing on the Korean variety show âWeekly Idol,â where K-pop idols frequently appeared. It involves dancing briefly to a specific part of a song, mostly choruses or dance breaks. The game is exciting to watch as participants donât know what song and which part will be playing, putting them on the spot.
Nowadays, random play dances arenât really conducted as a game anymore but more as a gathering for dancer fans during K-pop conventions or other events. With different fandoms being unified through the familiar dance steps and hit songs that get played on the streets, itâs fascinating to see people dance together to K-pop. This way, they get to show off their dancing skills while bonding with fellow fans.
Aegyo Challenge
In Korea, âaegyoâ is a term for acting cutely, often as a display of affection. This is done through babyish actions such as pouting, using a baby voice, and making cute hand gestures or facial expressions. K-pop idols are frequently asked to show their âaegyoâ as fans love seeing their cute sides. Although most idols feel shy doing it, they still grant fansâ wishes as a sign of appreciation.
Eventually, this developed into a challenge for idols when they appear on variety shows, sometimes used as a consequence if they lose a game. Even on TikTok, thereâs an aegyo challenge trend for idols and fans alike, including the âPoPiPoâ and âSorry for being cuteâ songs.
You might be able to relate to a few or all of these trends and challenges. Ultimately, they show how you celebrate your shared passion with fellow fans and connect with your favorite K-pop artists. In the process, you may even influence other people as well!
