If it's truly Gangnam Style, I think I just gained satisfaction in that boss fight against him in God of War 3.
EDIT: Yes, I. Hate. Gangnam Style.
Hillarious easter eggs at it's finest.
I'm pretty sure it was Jump On It. Gangnam is portrayed by having both arms in front and there's no turning involved.
Considering Gagnab Style's popularity, I believe it may be a reference. Nice find!
Also, to the poster who posted "Jump On It", the similarities in the two dances are uncanny!
