It's OppaN, actually, which means "father" or basically "an older authority figure". Combined with Gangnam it's basically an equivalent of "do it big" or "do it flashy" with rich style, etc etc. Yeah he actually went to school at Boston, so his English is pretty much native.
Wow, he performed with Madonna! Also funny that his dancing is so much better than hers. http://www.youtube.com/watch?v=56ogvcBnIqY
...damn. That video was quite...enjoyable. I have absolutely no idea what she's saying but that was a real fine video. xD Gangnam style is an exercise in mind control!
lol, very true! He is also very well spoken, seems like a very genial fella and has put in years of hard work to have this international hit. Good for him plus he's cute
