It's tiring to be asked the same questions all day long: 'What is Gangnam style?' and 'Teach me how to dance.'
PSYGangnam is a territory in Seoul, Korea. I describe it as noble at the daytime and going crazy at the night time. I compare ladies to the territory. So - noble at the daytime, going crazy at the night time - and the lyric says I am the right guy for the lady who is like that.
