Kat wikipedia pun ada pasal PSY ni..
"Gangnam Style" is a Korean language colloquialism that refers to a luxurious lifestyle associated with the Gangnam district, an affluent and trendy area of Seoul. The music video depicts Psy dancing at various locations in Gangnam. The song's theme is about "the perfect girlfriend who knows when to be refined and when to get wild."
In Korean colloquialism, "오빤 강남 스타일 (Oppan Gangnam style)" may be translated as "I am (loving) the Gangnam style." or liberally translated as "I am Gangnam style." or "A Gangnam-styled girl is my style." because the Korean word 오빠 (oppa), which is a noun meaning "a female's elder brother" but can be also used as a first-, second- or third-person masculine pronoun to designate a male who is elder or older than a female, is used as a first-person pronoun in this phrase and 오빤 (oppan) is an abbreviation of 오빠는 (oppaneun) which is translated as "I am" when 오빠 (oppa) is used as a first-person pronoun.
