매끈매끈하다 매끈매끈한

Sounds like 'Meh-kuhn-meh-kuhn-hah-dah Meh-kuhn-meh-kuhn-hahn'.

This meme first appeared on October 29, 2025, in episode 20 of the YouTube entertainment content 'Finding Kani'. It then began to gain explosive popularity on November 4, 2025, when 'Happy Pizza Bread' released a remixed version of the scene, quickly spreading as a challenge. It became particularly popular around the time of the Suneung (Korea's college entrance exam), earning it the nickname 'Suneung forbidden song'.

The 'Maekkeunmaekkeunhada Maekkeunmaekkeunhan' meme originated from an impromptu rap and dance created by Kani, a French choreographer, while she was memorizing Korean adjectives. It is characterized by its unique rhythm and choreography, featuring the repetition of adjectives like 'maekkeunmaekkeunhada' (smooth), 'pyeongpyeonghada' (flat, pronounced 'pyongpyonghada' by Kani), and 'ultungbultunghada' (bumpy). The combination of repeating the base and attributive forms of adjectives, a catchy melody, and Kani's distinctive pronunciation contributed to its widespread popularity.

This meme is primarily consumed by young generations, ranging from teenagers to those in their thirties. It rapidly spread among K-POP fandoms, especially as K-POP idol groups participated in the 'Maekkeunmaekkeun Challenge,' gaining significant popularity among YouTube, Instagram, and X (formerly Twitter) users who enjoy short-form content.

The 'Maekkeunmaekkeunhada Maekkeunmaekkeunhan' meme is primarily used by dancing to the original sound or by creating parodies featuring various characters or situations. It has been parodied in various content, including 'Kim Maekkeunmaekkeun' from the Kim Geun-yuk series, 'Ppodeukppodeukhada Ppodeukppodeukhan' from Princess Catch! Teenieping, Beast Friends, Republic of Korea Army, Black and White Chef, Hanako Nana, and Hachuroun Saenghwal. Furthermore, several K-POP idol groups such as SHINee Key, TWICE, BOYNEXTDOOR, Kep1er, and TWS have participated in the challenge, incorporating their unique styles.
