Fast Times

Chin2 (named after the original filename chin2.mpeg) is a humorous video that became a popular Internet phenomenon. The video features two shirtless Korean youths who dance and lip-sync along with a sped-up version of the Korean language song "Jung Hwa Ban Jeom" (중화반점 "Chinese Restaurant") by the Korean artist Louis.
The clip appeared around 2001 on Korean websites where the two performers gained the nickname, Chun Brothers (춘 브라더스), as they introduced themselves as Maeng Chun-sik (맹춘식) and Maeng Chun-sam (맹춘삼), which sound funny to Korean speakers. The two are actually close friends of the same age, (born in 1982), Choi Chang-guk (최창국) and Kim Jun-ho (김준호). The title of the clip probably comes from Chin-gu, the Korean word for friend.
Several imitators have since made copycat videos (e.g. Unchin2) with the same song, mimicking the original movements. The original pair also made similar videos, chin1.mpeg and chin3.mpeg, which are less well known. (Wikipedia -- the source of unsourced information)
