So now I have, and am sharing it with all of you who were either as clueless as I was, or who just need a little giggle today. Beautiful, lovable, yes you, hey, yes you!
According to Wiki, "the phrase 'Gangnam Style' is a Korean neologism that refers to a lifestyle associated with the Gangnam District of Seoul". The singer, PSY, has said, "People who are actually from Gangnam never proclaim that they are -- it's only the posers and wannabes that put on these airs and say that they are 'Gangnam Style' -- so this song is actually poking fun at those kinds of people who are trying so hard to be something that they're not.
"The song talks about 'the perfect girlfriend who knows when to be refined and when to get wild'. The song's refrain, 'Oppan Gangnam style', has been translated as 'Big brother is Gangnam style', with PSY referring to himself; 'Oppa' is a Korean expression used by females to refer to an older male friend or older brother. He studied hard to find something new and stayed up late for about 30 nights to come up with the 'Gangnam Style' dance. Along the way, he had tested various 'cheesy' animal-inspired dance moves with his choreographer, including panda and kangaroo moves, before settling for the horse trot, which involves pretending to ride a horse, alternately holding the reins and spinning a lasso, and moving into a legs-shuffling side gallop" (sourced from Wiki).
