You don't know, Jisung-hyung, you don't know

The phrase "You don't know, Jisung-hyung, you don't know" originates from a comment made by former footballer Lee Chun-soo. In an interview, Lee Chun-soo recounted his experience of Park Ji-sung, who was playing for Manchester United at the time, not being widely recognized by locals. He said, "Nobody knows. They don't know Park Ji-sung, they don't know Jisung-hyung..." This remark quickly spread across internet communities and later evolved into a meme that is humorously used in various contexts. It is particularly used when someone is unaware of a well-known fact or figure, often to tease or emphasize their lack of knowledge. Over time, this meme has spread widely online, incorporating different variations and humor elements.

This meme is especially popular among football fans and is actively used in online communities and social media. However, it has expanded beyond football and is now widely applied in different fields to humorously point out situations where someone is unaware of something well-known. The "They don't know Park Ji-sung" meme has thus become a unique comedic element in Korean internet culture.

The spread of this meme is also linked to Park Ji-sung's international recognition. Despite his global reputation from playing for Manchester United, some foreign fans might not be as familiar with him. This situation contributed to the transformation of Lee Chun-soo's comment into a meme, reflecting both the pride and humor of Korean football fans.
