VIDEO: Psy Learns What Herpes Is, Thanks Billie Joe Armstrong For Comparing Him to It


South Korean pop sensation Psy did his Gangnam Style all the way to the Met Gala.

Green Day frontman Billie Joe Armstrong went viral, so to speak, when he posted a photo of South Korean pop sensation Psy to his Instagram feed, accompanied by the caption, "This dude is the herpes of music. Once you think it's gone, it comes back. #herpes #flareup #pleasegoaway"

The "Gangnam Style" singer was informed of the putdown on a recent sitdown on Fuse.

After being explained what herpes is, Psy considered for a moment and replied, "I think it's cool."

He then thanked Armstrong directly for the metaphor.
