PSY's gangnam style-revealed

what does 'OPPAN GANGNAM STYLE,'
mean?
It roughly means something like 'Your man has
Gangnam Style.'
'Oppa,' which literally means 'older
brother,' is an affectionate term girls use to address
older guy friends or a boyfriend.
It can also be used
as a first-person pronoun, as PSY does here — in
this case, he's telling a woman that he has Gangnam style.

Korean city of Seoul. Where young peopl know how to party.
