gangnam is actually a district in south korea. the song's meant to be a send-up of the people there and their swag. their gangnam style
From what I've hear (I obviously don't speak Korean) it is a satirical song. I like it and people shouldn't be made to feel bad for something they like. I haven't bought it yet, but I may do in the future. It makes me happy

So happy it's doing so well worldwide, this should/could be the start of k-pop going mainstream!
